The first m ethod of Z ieglerN ichols is app lied to determ ine the initial val e of PID controller. And thro gh the speed and acc racy changes of the control system response c rve, sing the f zzy control theory, it can amend the in itial val e of PID con troller. Then the PID controller param eters are ob tained wh ich can m eet the control req irements. The smi lation res lts show that: th is method can q ick ly determ ine the param eters of K ,K ,K ; the in telligent control of the PID controller param eters are achieved. The validity and reliab ility of this determ ination p i d m ethod is verified.
