"Control Science and Engineering" is a discipline that studies the theory, method, technology and engineering application of control. It is one of the most important and fastest-growing disciplines in the 20th century, and its theoretical development and technological progress at all stages are closely related to the actual needs of production and society. My postgraduate major in Automation Department includes seven two disciplines, including control theory and control engineering, detection technology and automatic device, system engineering, pattern recognition and intelligent system, navigation, guidance and control, enterprise information system and engineering, and bioinformatics. The main research fields of the two disciplines and their relationships are as follows.

Control Theory and Control Engineering takes the control system in the engineering field as the main object, and takes mathematical methods and computer technology as the main tools to study the theories, methods and technologies of modeling, analysis, synthesis, optimization, design and implementation of various control strategies and control systems.

Detection technology and automatic device detection technology study how to convert various parameters reflecting the characteristics of the measured object into signals that are easy to transmit according to a certain corresponding relationship and provide them to the automatic control system; Automation equipment involves sensors, transmitters, controllers and actuators in the control system, including their integration, intelligence and reliability technologies.

This subject trains senior professionals engaged in the research, development and design of various detection technologies and automation devices.

This major focuses on industrial automatic control devices, system reliability evaluation and design, control system automatic test methods, data information collection, transmission, processing and conversion methods and corresponding equipment, new sensors and instruments, sensor data fusion theory and application, dynamic system fault diagnosis technology, industrial field bus technology, high-speed enterprise network composition and security technology, new high-power electronic devices and applications, embedded system research and related product development.

Pattern recognition and intelligent system is a new subject developed on the basis of signal processing, artificial intelligence, cybernetics and computer technology since 1960s.

This subject trains senior professionals engaged in the research, development and design of pattern recognition and intelligent systems.

This major focuses on the theory and application of pattern recognition, computer vision and machine intelligence. Theory and application of signal processing; Bioinformatics and modernization of traditional Chinese medicine based on information theory and technology: theory and application of intelligent control and intelligent system: neural network, fuzzy system, statistical learning theory and its application in information processing, identification and control.

Navigation, Guidance and Control Automation Department set up this major to meet the strategic needs of China's national defense development in the 2nd/Kloc-0th century, and attract more outstanding students who are interested in aerospace and national defense modernization to Tsinghua University for further study.

This major focuses on: 1. Theory and technology of precise guidance, navigation and control of moving objects; 2. Research on space exploration and on-orbit technology of aircraft; 3. Information interaction and processing technology of integration of heaven and earth; 4. Application of intelligent control and active control technology in aircraft design: 5. On-board (on-board and missile-board) computers, embedded systems and embedded application software; 6. Research on the application of virtual reality technology in space simulation: 7. Underwater acoustic countermeasure and guidance control of underwater vehicle.

Enterprise information system and engineering are two disciplines independently set up in our school under the first-level discipline of "Control Discipline and Engineering". The major of enterprise information system and engineering takes the economic carrier enterprises formed in industrial society as the research object, and studies the relevant theories, technologies and methods of applying information technology to transform their management model, business model, product design model and manufacturing model. Therefore, this major is an interdisciplinary subject based on comprehensive control, computer, management and machinery.

This major focuses on 1, modeling, control and optimization of complex manufacturing system 2, networked manufacturing 3, simulation and virtual manufacturing 4, modern logistics and e-commerce 5, theory, technology and methods of enterprise information engineering 6, advanced air traffic control system, etc. The goal of this major is to make a breakthrough contribution to the control of the development of science and engineering disciplines, to play a bridge and backbone role in the cross-integration development of various disciplines in the School of Information, to maintain the domestic leading and international first-class level, and to continue to play a traction and guiding role in the development strategy of "promoting industrialization with information" in China.

Bioinformatics has two disciplines, which are independently set up by our school under the first-class discipline of "Control Discipline and Engineering". The main academic direction is to use modern information and biotechnology to explore important life phenomena at the molecular level from the perspective of connection, evolution and system, and to seek their internal laws. At present, the research focuses on basic research around bioinformatics, such as analysis of genome organization and information structure and alternative splicing mechanism, genomics and protein omics of complex diseases, prediction and simulation of nucleic acid and protein structure related to genome information, protein function prediction, modeling and simulation of gene regulatory network, theoretical and experimental research of molecular network regulation of traditional Chinese medicine, information processing for bioinformatics applications, machine learning and high-performance computer research, and analysis of some important signal transduction mechanisms and drug targets by SNPs. In the future, other branches of disciplines closely related to bioinformatics will be prepared, such as molecular imaging and biological computing. The key laboratory has close academic cooperation and exchanges with many first-class research institutions in the fields of computing science, biology, statistics and medicine at home and abroad.

Personally, I think every major in Tsinghua is good and the employment is fierce. If you really want to compare one, I think biotechnology may be a bit cutting-edge, and everything else is good. All professional courses take the circuit test.
