Construction and Simulation of Fuzzy-PID Controller on Stepping Motor

In order to improve the performance of stepping motor system, the modern theory of fuzzy control and classical PID control theory are organically combined, the structure of fuzzy PID controller has built,which is suitable for the stepper motor control requirements, and corresponding control rules have designed that have realized the control of stepping motor. MATLAB software is applied for simulation. Comparing the fuzzy self-tuning PID controller with the conventional PID controller, the simulation results that fuzzy parameter self-tuning PID control system has less overshoot response, shorter reaction time. Fuzzy parameter self-tuning PID control has comprehensively improved the dynamic response performance of stepping motor control system, ensured the control accuracy.
