In order to study the dynamic performance of Permanent Magnet Synchronous Motor (PMSM) electric vehicle, a PMSM integrated control algorithm based on space vector and sliding mode variable structure is proposed. Parameters of vehicle matching, PMSM selection, space vector construction Mode and sliding mode variable structure controller design, and the establishment of vehicle simulation model for NEDC dynamic simulation analysis. The results show that the design of transmission ratio and PMSM power parameters of electric vehicle is reasonable. The space vector, sliding mode variable structure and integrated control method have good dynamic performance, good rationality and real-time performance, Comfort.
