说明：  空间矢量控制方式的实质是将交流电动机等效SVPWM为直流电动机，分别对速度，磁场两个分量进行独立控制。通过控制转子磁链，然后分解定子电流而获得转矩和磁场两个分量，经坐标变换，实现正交或解耦控制。
(Essence of space vector control mode is equivalent to SVPWM AC motor DC motor, respectively, speed, independent control of the two components of the magnetic field. By controlling the rotor flux and the stator current decomposition to obtain the torque and the magnetic field of two components, the coordinate transformation, achieve orthogonal or decoupling control.)
