Abstract
Aiming at the problem that conventional PID controller can not adjust paremeters itself on line,a method of PID parameter controller with fuzzy self-adjusting function is proposed based on fuzzy control technique.The result of simulation in fuzzy logic toolbox of Matlab proves that the controller possess both the precise character of PID controller and the flexible advantage of fuzzy controller,and can guarantee that regulation system has good dynamic and static quality.
