Abstract: To improve the speed control effect of permanent magnet synchronous motors, a method based on Fruit Fly Optimization Algorithm ( FOA) was proposed to optimize proportional integral derivative control. Among them, taking the PMSM speed control system as the background, a PID method for the speed control system was constructed, and then a PID controller with FOA optimized PID parameters was constructed to achieve adaptive control of the permanent magnet
synchronous motor speed system. The simulation results showed that the FOA-PID method had the characteristics of fast response speed, small overshoot, strong anti-interference ability, and speed regulation ability. Under the condition of changing the speed with a fixed load, it only takes 0. 02 seconds to reach a stable state, effectively improving the control performance of the permanent magnet synchronous motor speed control system. Compared to the standard PID and RBF-PID methods, the overshoot of the FOA-PID method under forward starting speed was 1. 36%, which was 5. 73% and 1. 12% lower, respectively; Under negative starting speed, the maximum overshoot of the FOA-PID method was 0. 56%, which was 15. 13% and 8. 22% lower, respectively. From this, it can be concluded that the FOA-PID method is feasible and has certain advantages.
