如何学好电液伺服和电液比例控制系统？

Well, do you need this for study or for application? In study, you should ask your teacher. For application, firstly, you have to know English well. Secondary, determine when to use proportional control, and when to use closed loop control. There are some figures:
1. If speed is higher than 200 mm/s with accuracy of 1mm -> proportional control
2. If position accuracy is less than 1 mm -> closed loop control
3. If speed higher than 500 mm/s, -> closed loop control
4. If pressure accuracy is within 5 Bar -> proportional contol
5. If pressure accuracy is within 1 Bar ; > closed loop control
If you can think of one or two reasons for the above requirement, we can contineu to discuss.

我也正在考虑这个问题。但是有电控专业的人跟我说只需要学好PLC会编程就可以了。我们是搞工程机械的，好像需要自动控制，但精度都不是很高。正在犹豫先学控制论还是直接学编程就好了?

5楼的，你的朋友说得对。工程机械的重量大都是几十吨重，又是人手控制，不是自动控制的，PID控制里只有P控制有用，所以应学编程，特别是和CAN总线相关的，非常重要。
在其他行业如重工、压机等等，则懂自动控制理论会有帮助。
