The mathematic model of electric vehicle(EV) driven by permanent magnet synchronous motor (PMSM) is established, on the basis of which, the performance simulation of developing EV is done including the acceleration, speed-variable running and so on.

• 在研究永磁同步电动机驱动系统的基础上,建立了永磁同步电动机驱动的电动汽车数学模型,并对拟开发电动汽车进行了计算机仿真,包括电动汽平路稳定转速运行仿真、变车速运行仿真等。
