In order to improve the performance of the speed control system of permanent magnet speed-regulated DC motor, a fuzzy PID control strategy is proposed. According to the basic rules of fuzzy theory, use Matlab to generate a fuzzy controller, select the actual parameters of the motor, combine the fuzzy theory with PID control technology according to the servo control strategy, use the center of gravity method for fuzzification, get the PID control parameters, and pass Matlab simulation contrasts the influence of fuzzy PID control and individual PID control on the signal. The simulation results show that the fuzzy PID control performance is better than the single PID control, which can meet the high precision and smooth operation of the DC motor.
