PID Controller Tuning For Multivariable System Based On H_∞ Control

Loop-shaping ~ method and how to chose the pre-compensator determines the performance of the closed-loop system are studied in this paper. In order to implement the complex H~ controller, we propose a method to reduce it to a multivariable PID controller. Simulation results show that Loop-shaping H0, method has good robustness for typical processes and it maintains the good properties of the original controller.We developed the software of PJD tuning for multivariable processes based on ~ control in Matlab.Hu Zhiqi (Control theory and control engineering)Directed by Prof. Zhang Luanying Tan Wen &Wang Yinsong...
