1. Introduce yourself

Apply for Zhejiang University 2022 School of Control Science and Engineering, majoring in electronic information, retest line 380.

The number of test contents is English 1, and the automatic control is 845.

Finally, I went ashore to master-> intelligent robot

The undergraduate course in Jiangsu is 2 1 1, and the major is automation, but there is no cross-exam.

The initial test score is 405, politics 69, mathematics 133, English 76, self-control 127.

Undergraduate competition research: the electric competition has the first prize in the country, the second prize in the provincial competition and the special prize in the school competition. The rest are relatively watery, basically second prize or something, with little gold content.

2. Analysis of the concept of controlling the entrance examination

The following is just my own analysis, which may be partial.

Generally, there are two specialized courses in automation for postgraduate entrance examination, namely, automatic control principle (+current control) and circuit.

I think I'm relatively good at automatic control and poor in circuit science, so I'll rule out the school in southeast Tsinghua where I took the circuit test. Although Tsinghua seems to have taken the test of automatic control, the direction is instrument. I don't think I'm interested or my undergraduate course is in this direction, so I don't want to apply, and my score doesn't seem to be high either. Look at your own needs. If you really have a dream about Tsinghua and study hard about circuits, I think it's ok to stick to it.

Further down are Harbin Institute of Technology and Zhejiang University. I am from the south, and my family is in Zhejiang, so I chose Zhejiang University and wanted to stay in Hangzhou.

About choosing a school:

Choice is greater than effort. When choosing a school, we should first consider our own strength, and then comprehensively consider the comprehensive factors such as the admission ratio, average admission score, subjects to be tested, professional re-examination and so on, and then choose a target institution within our own ability.

In the latest round of discipline evaluation, the control major of Zhejiang University is A+. Coupled with the popularity of artificial intelligence in recent years, many people apply for the control of Zhejiang University every year. /kloc-in 0/9, the number of control postgraduate students in Zhejiang University reached 500+, and 66 students were enrolled (33 masters +33 masters). 20 19 due to the large number of applicants, the score is high (35.

The difference between a master's degree and a degree: the degree is the same, but the master can take a doctor's degree, and the master must take a doctor's degree to study. So generally speaking, there will be more places for master's degree, and the average admission branch will be lower than master's degree (but there are exceptions, depending on the actual situation).

The postgraduate entrance examination subjects controlled by Zhejiang University are the same as those controlled by Zhejiang University, and they are all math I, English I, politics and professional courses. Specialized courses can choose to take automatic control principle or signal processing. , and Zhejiang University graduate students, professional master's independent marking is the same (initial test line 19 390 points). The college has different training programs for master students and master students, and different requirements for graduation (depending on different research groups), but there is no difference in tuition, accommodation, scholarship treatment and so on.

I don't have much experience in preparing English. Mainly memorizing words, writing compositions and doing real questions. I used Zhang Jian's yellow skin.

Politics, I started in September. I used Xiao Xiurong's excellent lectures and condensed exercises.

I watched the video of Xu Tao, which was very interesting. Read the chapter and do the questions. After watching politics for the first time, I used a small program to brush the questions and recite Xu Tao's recitation manual.

Mainly brush the questions, and you will know the answer when you see the questions. The big topic is to recite eight poems by Xiao Si Xiao. I recited Xiao Si, followed by Master Concabo.

The specialized course started late, but it had a little macro-microeconomic foundation before. I didn't read the book directly. I choose to watch videos and read the macro and micro foundations of Bing Zheng.

He will also talk about some special topics, and there will be orientation classes in various schools later. According to Mr. Bing Zheng, he has an accent. If you can accept it, you can talk to him. He speaks very well and is easy to understand. What impressed me was that I never understood what he said about the macroeconomic genre, but it was much clearer after reading his class. There are also three big books in Nankai, which cover all the real questions over the years. There are also some possible expositions, short answers and calculation questions, which I personally think are of high reference value.

Studying and reviewing I have basically been following Yu Ge's review class, which is more worry-free, and the teaching materials are also purchased. Later, I added various pre-test simulation questions and sprint questions, supplemented knowledge points and problem-solving methods. But every teacher has his own characteristics, and some teachers are also related to Tang Jiafeng, Yu Bingsen and Li Yongle. However, I advise you not to believe in the ghosts and gods of a few people, which is deceptive!

1) Bibliography:

Zhang Yu's thirty lectures on advanced mathematics,

Eighteen lectures, nine lectures on Zhang Yu's probability theory and Zhang Yuzhen's topic.

Various pre-test simulation questions, sprint questions.

2) Preparation process:

March-June: the first basic course. The basic stage is "Zhang Yu's Basic 30 Lectures".

Follow the video and take notes in the notebook (usually some summary knowledge points). This work is recommended to be done well in the early stage! It is most important to establish a good framework. At this time, in addition to completing the exercises after class, you can also do Zhang Yu's 1000 problem. In the basic stage of this exercise, you can start to do Group A and Group B.. )

June-September: the second strengthening. The reinforcement stage was taught by Zhang Yu's 18+9+9, followed by a video. In fact, it is suggested to focus on the intensive part or start early, because the knowledge of basic courses is really much less! Unless you don't learn math well at the undergraduate level, you can lay a good foundation from the beginning of the basic course. At this stage, Zhang Yu's "1000 problem"

Group A and Group B can continue to finish what they didn't finish. Group c can do it properly, and the workload is still very large. I will also watch some key chapters of the exercises to explain the video. At this time, I will increase the intensity of mathematics. I usually arrange the whole morning from 8: 30 to 12, so I suggest matching the time of postgraduate entrance examination and leaving enough rest time at noon. (I used the old version of 1000 to divide the questions into abc groups)

Note: in the strengthening stage, we should summarize the wrong questions and review them regularly; Exercise must be calculated by hand and avoid arrogance; Develop the habit of planning and using draft paper, because exams are taken one by one; Problems you don't understand should be solved on the same day or you will forget them later; Some questions in Zhang Yu 1000 C group are very skillful and can be put away properly.

9- 165438+ 10 month: the third real question and simulation. The first task at this stage is to simulate with real questions. The purpose is to connect the knowledge points before and after and simulate the feeling of doing the questions in the examination room. At the beginning, I used the real questions from 2005 to 2009 (the structure of the real questions in recent years is still the old version) to connect knowledge points in series, so I didn't have time to do it. I am familiar with the feeling of solving real problems, and continue to summarize the wrong problems. After that, I will do the real problem of 10 -20 years. I have to do it in time at this time, and I will finish one in about 2.5h hours. Then I must check it! Prepare your own draft paper and answer sheet, and use the morning time to simulate the math exam. The number of real questions is limited, so make good use of it! ! After finishing, calculate your own score and make a summary of the wrong questions and papers. 2 1 changed the question type. This year, the focus is on simulation to ensure that you are familiar with the time allocation of the whole problem. If you have enough time, you can do the second round of real questions (I don't have enough time, so the second round is basically wrong and I didn't do the whole set)

1 1 before the exam: simulation questions and sprint questions and knowledge consolidation. Because the questions and scores have changed, it is very important to do simulation questions. Based on the transparency of the real problem, you can start to do the simulation problem. 8 sets of simulation questions can be selected, including Li Lin, Zhang Yu, Polytechnic University and Li Yongle. I basically did it at that time. I felt that Li Lin did it more like a real question, Li Yongle paid more attention to calculation, and Zhang Yu and Gong Da were a little more difficult, but the idea was worth learning. Choose 1-2 kinds of simulation questions and sprint questions. Another important thing is to consolidate the knowledge framework. At this time, the summary notes of the basic stage are used, and of course they are constantly improved during the review process. In addition, if you still have time to read the wrong questions again, you can almost take the exam. You must relax on the day of the exam! ! ! Getting the right score is victory ~ I was struggling with a big question, not only did I not make it, but I didn't have time to check it, so I lost the score of a simple question in vain.

Math:

The importance of mathematics and specialized courses in the initial examination of postgraduate entrance examination is self-evident. For preparing for the math exam, I think it doesn't matter which tutorial book to use and which teacher to learn from, Zhang Yu (I chose the exam), Li Yongle or Li Lin. Teacher Zhang Yu's topic will be more difficult, while teacher Li Yongle's counseling book pays more attention to the basics, and teacher Li Lin seems to be more powerful.

Many people will spend a lot of time watching math videos. Usually, if you are tired of doing the problem, just watch Zhang Yu's high-level intensive class video to relax. I think learning math well depends on doing problems. There are not too many questions, but we should improve the efficiency of doing the questions, especially when doing the real questions. I can brush the real questions several times (I have done the real questions twice). When doing real questions, we should sum up the style of real questions and try to figure out the intention of the questioner.

At the end of the postgraduate entrance examination, you must simulate the exam in strict accordance with the time of postgraduate entrance examination, take every test paper seriously, and make a real test paper every few days. For the wrong questions, we must thoroughly understand the reasons and master them thoroughly. Don't take chances, think that this mistake is due to carelessness, and you will still make mistakes in the examination room (my painful lesson).

Professional courses:

Teaching materials for specialized courses are very important, so it is best to buy the teaching materials of the seniors who have been admitted.

The real questions of specialized courses are also extremely important. After fully mastering the knowledge points and after-school questions in the textbook, you can start to brush the real questions. When doing real questions, we should also strictly follow the time of the exam. The more real questions are, the more important they are, and every question on the real questions over the years should be thoroughly mastered. Remember to summarize the teacher's style and exam focus in that school when you do the real questions in the specialized courses. The real questions of professional courses should be brushed at least once every year (I brushed them twice)

In the initial test, there is generally little difference between English and politics, which is particularly easy to open the difference between mathematics and professional courses. Therefore, if you get high grades in math and professional courses, the total score will not be too low. I hope everyone can pay attention to math and professional courses.

English:

Vocabulary is the key to English postgraduate entrance examination. Every morning at a fixed time or before going to bed, you must recite the vocabulary of the postgraduate entrance examination, over and over again. I recite it every day from preparing for the exam to the exam, without a day off. The form of memorizing words is not fixed. You can recite it on your mobile APP or word book. If you use a mobile phone to recite, you should resist the temptation of the mobile phone. I use the little red book.

Start doing English real questions at 5438+00 in September or June. When doing real English questions, we should strictly follow the time of the exam, and the order of doing the questions is also very important. It is best to write a composition first, then reading comprehension, new questions and translation, and finally cloze. Reading comprehension is the most important thing, and the reader wins the world. When doing real English reading comprehension, we should pay attention to the style of reading questions and options, and try to figure out what the questioner is digging. In the allocation of time for doing the questions, the size of the composition is 60 minutes, the reading comprehension is 60-70 minutes, the new question+translation is 30 minutes, and the cloze can be done faster, not more than 20 minutes.

Politics:

Re-examination: Don't think too much about it now. What you need to do is to get the highest score in the initial test, the better. The proportion of re-examination controlled by Zhejiang University is higher than that of initial examination (about 1:3), so the re-examination is also extremely important.

About choosing a school: I personally think that the higher you want to choose a school, the better. With the in-depth review later, if you think you may not be good enough, it is also feasible to consider lowering your goals. If you think you are ok, you should stick to it. If you lower your goal, you will feel less pressure. For example, I started to watch the specialized courses of Zhejiang University, and then I went to my classmates to watch the specialized courses of our school after watching the specialized courses. I feel that most of them are a blow to the dimension.

3. Analysis of specialized courses

Why do you talk about professional courses first? ? Because in fact, most of the 985 exams are in English, and the difference is mainly reflected in professional courses, and don't underestimate this difference, which will be discussed in detail below.

Analysis of specialized courses in Zhejiang University:? Let's not say 2022, because 2022 has changed a lot.

Attention:? Zhejiang University does not take frequency domain corrections, such as leading and lagging. Zhejiang University did not test the phase plane, but the description function, but the description function was tested many years ago, and it is particularly simple. Just learn the description function a little. The research content of current control in Zhejiang University is more and more in-depth, and there are basically some things to understand.

Overall:? Generally speaking, the specialized courses of Zhejiang University are not difficult, at least I think it is a little simpler than Harbin Institute of Technology in previous years.

The exam in 2022 is strange: basically give up the first two questions directly. The first problem is to correct the use conditions before testing, and the second problem is to prove whether the zero-order keeper and delay link are nonlinear. I feel like I can do it in the back. One problem is mainly about the combination of Lissajous graphics and circuits.

It is difficult for me to understand that problem. In the end, I calculated it three times and didn't work out a parameter. I feel very strange, I don't know what the final answer is. However, judging from the final score, the overall score is not low.

Calculators are not allowed to be used in 2022. It seems that it has been banned since 202 1. I wonder what will happen in 2023? In 2022, the current control and decentralization accounted for a large part of the problem, and the root track in the impression was not tested. Generally speaking, not only the questions are strange, but also the contents of the survey are strange.

4. Formal experience post:

The time I give below is practical, but imitation is strongly discouraged. Generally speaking, study hard and take your time. There is always enough time.

The review time begins in April.

April to May: Review math (advanced mathematics) and recite English words.

The first half of June: review math (line generation) and English words and start some professional courses.

Next month after June: review the content of the course exam.

July to August: internship+tinkering, just intermittent study, slow progress. It should still be slow and steady.

September ~ 10: I feel that time is a little too late. I have to hurry up and read. I have forgotten what I learned before for a long time. I review+study mathematics (probability theory), continue to study specialized courses+strengthen. Read English every few days.

165438+1the first half of October: I went to play an e-sports game and didn't rest for a few days.

1 1 The second half of the month: watching politics, Xu Tao watching Ma Yuan, mainly watching Sister Leg's class and some skills. 65438+February: I totally feel that it is too late. Mathematics: sorting out the previous wrong questions+doing mathematical simulation questions+doing real questions. Recite English composition, politics and continue to watch the leg sister course.

Generally speaking, there will be several rules anyway:

-1. Probability theory does not recommend starting too early, and many formulas are easy to forget. You can even start looking at probability theory in two rounds.

-2. English words must be started at the earliest, and words should be memorized as soon as they are reviewed.

-3. Politics can't be earlier than September, and you can't teach yourself blindly and follow the teacher.

-4. The content of the course of automatic control principle is not too much, and it is completely in time to start school in July. A good September of this science is also ok.

4. 1 Mathematics

Math video:

-the main line is Zhang Yu, and I have basically watched Zhang Yu's classes.

In addition, I watched Wu Zhongxiang's intensive advanced mathematics class. I feel that the content of lesson 17 is similar to the intensive reading course of advanced mathematics, so I didn't read much.

-The line generation saw the intensive courses in Li Yongle, and found them very good and of high quality, which was highly recommended.

I didn't see anything of high quality in the probability theory part, so I had to do it myself. I didn't see anything except Zhang Yu in probability theory.

Watch the video misunderstanding:

-1. Every time I watch a video, one of my classmates will stop and make an example by himself, and then play it again. This is not recommended, and the efficiency is extremely low. The purpose of watching videos is to quickly master some questions and methods. Even if you can't do anything in this chapter, as long as you can keep up with the video, just keep watching it and watch the whole section before you do it yourself.

-2. You must not just watch the video without doing the questions. Doing a problem is completely different from watching a video. Video will lead you in the right direction, but a brand-new problem is likely to be completely covered up. Just because you can follow the video does not mean you can do it.

Book recommendation:

Zhang Mathematics 18: The quality is quite high, but it does have a problem. After learning, you must have the ability to identify partial questions, because some questions do have a small probability of being admitted, and you can't remember such questions after you answer them. I suggest giving up and sorting it out. Wait until 65438+February to go again. If you still can't do it, remember its thinking and just move hard before the exam.

Zhang Yu 1000 Question: It is suggested to do the high number part, which is the same as Zhang Yu's high number 18.

Please click to enter a picture description.

Tang Jiafeng 1800 Question:? Do all the basic parts, and don't suggest or pick topics to do the later strengthening parts. At that time, I chose to fill in the blanks in the reinforced part, and I chose some topics for the big questions.

Lin li 880: Very high quality, suitable for most students. There are few digressions, basically single digits. Better do it all. Because of lack of time, I only did line generation and probability theory.

Wu Zhongxiang's instruction handout:? If the quality is high, it is recommended to cooperate with the video and do it all.

Li Yongle tutorial handout:? With the high quality of Wu Zhongxiang's tutorial, it is recommended to watch and do it together with the video.

4.2 English

Video recommendation:

Jing Tian's grammar class.

Please click to enter a picture description.

Teacher Zhu Wei's word class, I suggest reading the previous edition.

Please click to enter a picture description.

Tang Chi's English reading class.

Teacher Tang Jing's translation class.

Please click to enter a picture description.

Teacher Pan Yun's composition class is written in Jiugongge.

Jing Tian's grammar class: I think it's very good. Although I don't actually remember much, some of the ideas or skills are very helpful for analyzing long and difficult sentences. Analysis of long and difficult sentences in postgraduate entrance examination sometimes does not require good grammar, and it can be well solved through some segmentation skills or something.

Teacher Zhu Wei's Word Class: As far as the version I watched at that time is concerned, Mr. Zhu Wei actually taught English well and the class was lively. Moreover, she also gave examples, which indirectly trained long and difficult sentences and a sense of language. I think it is very helpful for my future reading. But it does encourage some negative things, just ignore them. However, the video is really long. I suggest you read it when you recite the words in the early stage. If you start memorizing words during the summer vacation, I suggest you don't watch Zhu Wei's video class.

Teacher Tang Chi's English reading class: some skills of telling real questions, thinking from the questioner's point of view, etc. Can help us jump out of the topic and do English reading from a higher dimension. Sometimes you really need to read articles to know how to choose. However, some methods are quite different from those of Mr. Tang Chi. I'll read the full text first and then the topic, and do it one by one. Teacher Tang Chi basically reads the topic first, then the article, and then does it.

Teacher Tang Jing's translation class: To be honest, I didn't learn anything, more because I didn't absorb anything, maybe I was too poor, hahahaha. But I probably know what translation is about, and what kind of answer the questioner wants us to give. At least when doing translation questions, even if you can't, you don't panic.

Pan Yun's composition class: Very good. Bring the template and you can use it. Bring it to you! You can get your own universal template without modifying anything, which is very common for people like me who are lazy and pressed for time.

Book recommendation:? True questions and word books are enough. The real questions on the market are mainly the yellow book and the truth of postgraduate entrance examination. I use the truth of postgraduate entrance examination myself, and it feels good. Every sentence is translated and analyzed. I bought two word books: the first one is a love story, which belongs to teacher Zhu Wei. Mainly with video lessons, the second is little red book, and the next few months are mainly full-word little red books.

4.3 Politics

My politics is too poor, so I won't write in detail. Ha ha ha ha. However, I can still recommend Sister Leg a little. Her skills class is really great.

4.4 Automatic Control Principle Specialized Course 845

Please click to enter a picture description.

After reading the analysis of the professional courses mentioned above, you can look at this part.

Book recommendation:

1. highlights of automatic control principle postgraduate entrance examination: this book is particularly good, with complete knowledge points and few mistakes. It is highly recommended to buy, and it has a wide range of applications, no matter which school you take the exam in.

Write at the end:

The road of life is still very long, and the postgraduate entrance examination is only a small part of it, so you don't have to be too obsessed with temporary gains and losses. What others value is the result, but they have to undertake the process, so take care of yourself, don't catch a cold, play mobile phones less and exercise more. If you feel lonely in the postgraduate entrance examination, you can find a like-minded research friend, but please don't give up easily!

Finally, I wish all the students who took the postgraduate entrance examination success! All efforts will eventually pay off!
