根据幅相裕度整定IMC-PI控制器参数

Tuning IMC-PI Controllers Based on Gain and Phase Margin

基于内模控制思想的PID参数整定,所需整定的参数只有滤波器参数一个,而且该参数直接与闭环系统的响应速度及鲁律性相关。本文提出根据幅相裕度的要求来确定滤波器参数,仿真表明该种方法能带来较好的控制效果。

Tuning PID controllers based on internal model contro1,only parameter of wave filter need to be tun- ing,the parameter relates directly with both speed and robustness of respond, This paper present that the param- eter could be tuned according to gain and phase margin,simulation shows that using this method optimal control quality could be obtained.
