伺服系统中系统结构可变的二自由度PID控制

The two-degree-of-freedom PID control with variable control structure in servo system

阐述了系统结构可变的二自由度通用控制系统 ;依据伺服系统的应用 ,推导了二自由度控制器的设计与调整方法 ,给出了试验结果 ,展示了它的跟踪性能及抗扰性。

The two-degree-of-freedom PID control system with variable structure has been introduced in this paper. Its design and tuning method are also proposed according to the application in servo system. The result of experimentation shows that it can do the performances of both anti-jamming and tracing.
