| 中文摘要:阐述异步电机的矢量控制原理，对三相异步交流电机矢量控制系统控制过程进行MATLAB仿真，根据交流电机坐标变换及矢量控制理论提出异步电机在任意同步旋转坐标系下仿真结构图的建模思想，提出一种按“角速度-定子电流-转子磁通”为状态变量在动态坐标系下的动态结构图。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。仿真结果符合电机实际运行特性，证实采用该系统对三相异步电机进行控制，具有转矩波动小，转速响应快，超调量小等特点，运行性能良好,为实际系统的设计提供理论依据。 |

| Abstract:This paper expounds the control principle of asynchronous motor vector ,shows the simulink process of three-phase asynchronous motor vector control system with MATLAB, according to AC motor coordinate transformation and vector control theory, the paper puts forward induction motor in any synchronization reference frame into the simulation of structure modeling, and draw the dynamic structure uses as state variables in the coordinate. It is convenient to use the structure to build the motor of the simulation model and calculation.The results is coincident with the practice, demonstrate this system has the characters of small fluctuation of torque，quick response speed and smaller overshoot，the performance is favorable. It provides theory basis for the design of the actual system. |
