Research on Speed Tracking of Asynchronous Motor Based on Fuzzy Control and Vector Control

To improve the speed tracking effect of the three-phase asynchronous motor under different load conditions, a fuzzy adaptive PID controller is designed, which is based on the fuzzy control algorithm and the vector control algorithm. The motor speed curve is designed to avoid the influence of load inertia by using the trig function acceleration and deceleration trajectory planning algorithm. The speed control system model of the three-phase asynchronous motor is built by MATLAB/Simulink. The conventional PID controller and fuzzy adaptive PID controller are used separately, and the speed tracking effects are compared with each other. The results show that the fuzzy adaptive PID controller can achieve a better speed tracking effect and have strong robustness. The asynchronous motor can get a better speed tracking effect according to the given speed curve.
