Abstract

Controller design for multivariable processes is studied based on loop-shaping H∞ control. In order to implement the complex H∞ controller, a method to reduce it to a multivariable PID controller is proposed. A method to choose the precompen sator that determines the performance of the closed-loop system is put forward. Simulation shows that the designed multivariable PID controller has good robust stability and performance. MC-SLab-software for controller designing of multivariable processes is proposed.
