Simulation of surface mounted PMSM Vector Control Based on Fuzzy PI control

Abstract

Permanent magnet synchronous motor (PMSM) is a nonlinear, strong coupling and time-varying parameter control system. Although conventional PI regulator can realize the vector control technology of PMSM, it can not adjust the changing parameters of the system in real time. Therefore, this paper combines PI regulator with fuzzy control theory to realize the vector control technology of PMSM through variable fuzzification, fuzzy reasoning and defuzzification, Compared with the vector control simulation model of conventional PI regulator, it can be clearly found that the vector control based on Fuzzy PI regulator has faster response speed, stronger anti-interference performance and other functions, and is more in line with the high-performance driving requirements of PMSM.
