Study on controlling and simulation of drive system for permanent magnet synchronous motor in electrical vehicle

Ping Li, Lan Cao

Abstract

The Permanent Magnet Synchronous Motor (PMSM), which has high efficiency, high power density and good timing performance, becomes the first choice for the EV drive motor. The vector control system of PMSM used to drive EV is studied in this paper. Firstly, the mathematical model of PMSM vector control and coordinate transformation is analyzed. Secondly, a simulation model based on MATLAB/Simulink is established, and the control strategy selected is simulated, and analyzed the simulation results. The preliminary experimental results are obtained, which lay a good foundation for the subsequent research and development work.
