Abstract

permanent magnet synchronous motor (PMSM) has the characteristics of high efficiency and energy saving, high power factor, simple structure, high speed regulation precision, straight efficiency curve and so on. So it is very important to study the optimal strategy of high performance motor control system.This paper mainly analyzes the principle and vector knowledge of permanent magnet synchronous motor for electric vehicle. Several optimal control strategies are proposed for PMSM.
