异步电机的双闭环控制
说明： 矢量控制是目前交流电机的先进控制方式，一般将含有矢量变换的交流电机控制都称 之为矢量控制，实际上只有建立在等效直流机模型上，并按转子磁场准确定向的控制，电机才能获得最优的动态性能。
矢量控制的基本思路是以产生相同的旋转磁动势为准则，将异步电机在静止三相坐标系上的定子交流电流通过坐标变换等效成同步旋转坐标系上的直流电流，分别加以控制，以达到直流电机的控制效果。(Vector control is an advanced control method of AC motor at present. Generally, vector control is called vector control. In fact, only based on the equivalent DC motor model and accurately oriented control according to the rotor magnetic field, can the motor obtain the optimal dynamic performance.
The basic idea of vector control is to generate the same rotating magnetomotive force as the criterion. The stator AC current of asynchronous motor in the static three-phase coordinate system is converted into DC current in the synchronous rotating coordinate system by coordinate transformation, and then controlled separately to achieve the control effect of DC motor.)
