It has features of convenient adjustment and good control effect. For conventional PID control, it can’t get more technical staff make use of, and adjust the parameters of the process is very cumbersome, it not only take a long time for adjusting, but also it is very difficult to get the ideal results waveform, in practice, it is more difficult than the simulation。 In this paper, the application of based on fuzzy PID parameters self-tuning method, in Simulink, simulation and analysis of its results, the first of the traditional PID control simulation program, after repeated adjustment parameters obtained more satisfactory results, followed by the use of fuzzy PID controller program , simple and fast ideal waveform obtained by comparing the simulation results of the two programs, drawn fuzzy PID control scheme to meet the fast dynamic response, while not only did not overshoot, but did not oscillate, the system quickly to stabilize state, and continued to maintain a stable, indicating the feasibility of this scheme. For with large delay,time-varying and nonlinear complex control system, a fuzzy PID controller played a key role in the process of modern industry.
