I didn't know much about automation when I filled in my volunteers. I just got a rough idea from Baidu. I know this is a subject that studies automatic control. The word automatic control is in line with my love for engineering, so I filled in the automation major. I began to care about the introduction of automation in the summer vacation after filling out my volunteers. One of the biggest feelings I got from many introductions is that the scope of automation major is very wide, and the content involved is much more than other majors. But until the introductory course, I still didn't have a systematic, comprehensive and in-depth understanding of my major.

Fortunately, the school opened the course of Introduction to Automation, which made me have no vague understanding of my major in the freshman stage. In previous classes, Mr. Jiang Daming talked about the current situation and future development trend of railway traffic in many countries, especially the speed-up of high-speed rail, and emphasized that China railway wheel traffic is in a stage of rapid development, making an unprecedented leap forward and stepping into the forefront of the world, which makes us full of confidence in our professional prospects. Then Mr. Jiang introduced the ranking of our school's automation in the national colleges and universities, and told us that the automation of Jiaotong University, especially the railway automation, is leading in the national colleges and universities. I also know that our automation major is the most funded major in the school, which makes me full of confidence in the automation major. Mr. Jiang's several classes aroused our interest in the major, and we also learned the basic situation of the industry and had a basic understanding of the future development direction.

After that, Mr. Hou's class mainly introduced the professional content of automation, and briefly explained some theoretical knowledge, which was easy to understand. At first, he introduced us to many great scientists, including http://www.LWlM.cOm, a mathematician whom I admire most. Then, the classical automatic control theory and modern control theory are briefly introduced. They are different from drama systems, and the latter is more complicated, including optimal control, system identification, adaptive control, robust control, predictive control, filtering and estimation. After attending the lecture on mathematical modeling, I found that optimal control is an application direction of mathematical modeling. My interest can complement my major, which makes my determination to learn mathematical modeling more evaluated. I talked about many theories and formulas in several classes, but I didn't really understand them, but robust control left a deep impression on me, which made me come into contact with this feature for the first time and remembered the word robust.

Through this half-semester Taoist course, I have a comprehensive understanding of my major, a preliminary understanding of professional knowledge, a certain degree of understanding of the current situation and development of the industry, and a preliminary plan for my future career. Knowing this, I can know what I want to do as a freshman and pave the way for my future professional study, which has benefited a lot.
