Aiming at the high precision turntable control system, the fuzzy PID based on direct closedloop control method was proposed around its control frame and strategy. Simulation of fuzzy PID controller was proceeded herein for stepping motor, the superiority of fuzzy PID method in stepping motor direct closedloop control was testified. To solve the steps losing, started shaking, run drift and etc problems in traditional control method, the absolute grating ruler position error and error rate were taken as inputs, the error influence was eliminated further. The experimental results show that the system obviously has remarkable superiority in positional accuracy, meanwhile the reliability is satisfied.
