Abstract:

A fuzzy PI control method based on genetic algorithm was studied, and the fuzzy rules were optimized by genetic algorithm. The simulation results show that the improved algorithm has better control performance on the speed control of permanent magnet synchronous motor. Compared with the classical fuzzy PI control algorithm, the improved fuzzy PI control algorithm has better performance and faster response.The stable control performance is better for the sudden loading, and the improved fuzzy PI control system has better anti-jamming performance.

Key words: permanent magnet synchronous motor (PMSM), genetic algorithm, fuzzy rule, fuzzy PI control
