Application of a Fuzzy-PID Control Method to Synchronized Control of a Multistepping Motor

摘要

The synchronized operating system of multistepping motors is widely applied in industry. In this paper, a method of Fuzzy-PID control based on fuzzy control educed from the conventional PID control method is introduced. The stability of synchronized operation of multistepping motors can be improved with this method. The simulation analysis based on practical stepping motor parameters shows that this method is simpler and not only has less overshoot but also a shorter setting time than the conventional PID controller. At the same time, its steady-state characteristics and robustness are preferable. This method is easy to implement and has good performance making it possible to apply Fuzzy-PID control in many practical situations.
