Depending on which major you want to take, Hoda University of Telecommunications has two majors similar to yours: automation and electrical automation, which are slightly different. Professional courses mainly review analog electricity (children's) and digital electricity, and then the textbook of automatic control principle of Hebei University Electric Power College. It's best to go to school to buy old textbooks from the previous session. Many notes belong to Mr. Zong Xiaoping. You can ask at the Zhao Yan Forum, where there are many students from Hoda University. I graduated for two years, and now I don't know what the specific textbook is.
