I tell you, yes, the deeper part of automatic chemistry is mathematics. I graduated from automation graduate school. When I was a graduate student, I didn't have to take math classes. Many professional courses were basically mathematical formulas. You should feel lucky to be able to do anything after learning math well. Of course, this mathematics refers to applied mathematics, computer work, automation work, budget, production management and financial work. This is what a teacher in my university told me. He taught us the course of programmable regulator. At first we thought he was automatic. Later, he said that he graduated from the Mathematics Department of Zhejiang University. He told us that he could do anything after learning mathematics. So I made a plan long ago. If I have a child in the future, I will let him learn math. Therefore, if you study automation as a graduate student in scientific mathematics, you will have great advantages, and your tutor is willing to have such students, because many students who study automation have poor mathematical foundation, so it is more troublesome to start research (because there will be many theories and formulas).

During your undergraduate course, you should study by yourself in addition to majors, automatic control (Hu Shousong's version is recommended) and computer control. Generally, the professional course you want to take in the postgraduate entrance examination is one of this period, and it is best to learn automatic control. After all, you are interested in automation, so it shouldn't be difficult for you to teach yourself these courses. If you are interested, you can read the books on electrical automation again and get to know it. Not bad.

The courses to be tested in the postgraduate entrance examination are: politics (study hard when reviewing for postgraduate entrance examination, which can be ignored at ordinary times), English (four years in college, never giving up learning English, persevering, memorizing some words every day, taking CET-4 and CET-6 exams), mathematics (advanced mathematics, linear algebra, probability statistics), and specialized courses (different schools have different requirements, and generally choose one from several professional courses).

You are very lucky. If I had known this, I would have studied mathematics as an undergraduate. When I took the postgraduate entrance examination, my tutor saw that my math score was good, so I taught myself automatic control and other related courses. 90% of my tutors are willing to take you. Anyway, when I was interviewing for the postgraduate entrance examination, many tutors asked, how about mathematics? If there is a math major, our tutors there are rushing to get it.

Now I always feel that because the foundation of mathematics is not very good, professional courses seem to be more difficult (all formulas), and my heart is particularly lacking. Dude, you hit the nail on the head. You are the blessing of eight generations of ancestors!

PS: You can look at the textbooks on automation. Many people who write textbooks are from mathematics, especially from abroad.
