Fuzzy PID tracking performance for ball and beam system

This paper presents a design of Fuzzy PID controller to control the position of ball and beam system. The design objective is to improve the transient performance and to evaluate the controller ability to track a sine and square wave input signal. Fuzzy controller is proposed to overcome the problem of PID controller especially in obtaining optimal parameters. The effectiveness of the proposed controller was verified by simulation and compared with a PID controller obtained using PID auto-tune function in Simulink Toolbox. The results from step response and input tracking show that the proposed controller had a better performance in both evaluations compared to PID.
