摘要
基于纯电动汽车低速下的行车要求及永磁同步电机的结构特点,分析电机低速下转矩输出实现采用的最大转矩电流比控制方法;利用Matlab/Simulink工具对控制算法进行仿真分析。仿真结果证明这种控制方式可以满足电动汽车低速大转矩的行驶需求。
Based on the requirement of pure EV for low speed running and the structural characteristic ofpermanent magnet synchronous motor, the method of maximum torque per ampere control at low speed is analyzed,and the control algorithm is analyzed in simulation with Matlab/Simulink. The simulation results prove that thismethod can fulfill the requirements when pure EV runs at low speed and high torque.
