Abstract

PID controller is widely used in industrial practice, but its weaknesses limit its performance in some controller performances such as disturbance rejection or set-point tracking. In this paper, we propose a maximum noise entropy controller (MENC) based on the principle of maximum entropy. The basic model is based on noise entropy which is performance target. Maximum noise entropy controller could reduce the disturbance effect and increase the system’s stability. The simulation result shows that the controller is better than IMC-PID controller in the performance of disturbance rejection.
