电动车用异步电机启动阶段的仿真研究

Simulation Study of Starting Phase of AC Motor Used by EV

该文介绍了驱动电动车用异步电动机的三种控制策略 ,并采用MATLAB对异步电动机的仿真模型 ,在三种控制策略下进行启动阶段的仿真研究。仿真研究显示 ,直接转矩控制系统结构简单 ,且对电机参数不敏感 ,转矩控制性能好 ,适用于电动汽车。

In this paper, there are three control strategies of the AC motor introduced and implemented by the tools of SIMULINK . Through the simulation results of the AC motor which controlled by the control strategies , it shows that the DTC(direct torque control) has better performance ,and it suits with the AC motor used by EV.
