Abstract
The traditional PID control will easily show inferior dynamic and static state performance with oversize adjustment in a disturbed condition. Using the fuzzy-PID control method which is combined the PID control and fuzzy control can adjust the parameters of the PID controller on-line. The result of simulation by the MATLAB/Simulink software shows that the fuzzy-PID control has a better dynamic and static state performance than traditional PID controller with higher anti-disturbtive capacity of the control system.
