Study of Simulation for Direct-torque-control of Permanent Magnet Synchronous Motor

在以转子速度旋转的坐标系中建立永磁同步电动机的数学模型 ,针对整个交流传动控制系统进行建模 ,详细介绍一些关键环节的实现方法 ,并借助Matlab软件进行仿真 .对仿真结果的分析表明 。

This paper puts forward the mathematical model of Permanent Magnet Synchronous Motor (PMSM) in the rotor reference frame at first, and then models the whole ac control system, elaborates the realization of some key parts, and simulates it based on software of Matlab. Through analyzing the simulation results, it can be seen that the strategy of Direct Torque Control (DTC) has good control performance.
