本文系统而简略的阐述了异步电机的矢量控制原理，根据交流电机理论及异步电机在任意同步旋转坐标系下仿真结构图的建模设想，得出了一种按转子定向磁场下的动态结构图，利用该结构图可以方便的构成电机的仿真模型，进行仿真计算。最后以实际电机为例，对模型进行了仿真分析，结果表明电机有良好的稳、动态性能。关键词： 异步电机 矢量控制 数学模型 仿真Abstract: In this paper, a dynamic diagram of an induction motor is proposed in a synchronously rotating frame of reference according to theory of induction motor. This simulation model used to simulate an induction motor can easily be constructed from structure diagram. Finally, the experimental results are given from SIMULINK by using an actual motor.Keywords: Induction motor Vector control Model Simulation
