Abstract: The paper uses hysteresis relay feedback control to get the critical point parameter for the dead -time of processes, and tuning the initial values of PID controller through a given phase margin rule, then combining online tuning PID parameter by fuzzy inference. This method efficiently makes use of expert experience in PID parameter tuning, and the controller has the merits of both fuzzy control and PID control. Simulations show that this control strategy is very good at control performance, and it is simple and practical method for realizing a automatic industrial controller.
