模糊—PID复合控制在旋转伺服系统中的应用

The Application of Fuzzy-PID Controller on Servo System

在对旋转伺服系统的非线性和不确定性等特点分析基础之上,保留了PID控制静态稳定性能,结合模糊控制动态性能好的特点,提出了模糊、PID复合控制系统,即在误差大的时候,采用模糊控制,误差小的时候采用PID控制。实验曲线表明,该控制算法可以获得满意的控制效果。

Based on the analysis of the revolving servo system, a combined controller is developed . The controller keeps the strong suitability of the PID controller, which has a good static state performance. And it also makes use of the fuzzy logic controller, whose dynamic performance is rather good. After using the combined controller, a satisfying control performance of the servo system can be gained. The experiment image definitely proves it.
