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，以转子磁通定向，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(The velocity and magnetic field components are controlled independently. By controlling the rotor flux, the rotor flux is oriented, and then the stator current is decomposed to obtain two components of the torque and magnetic field. Orthogonal or decoupling control is realized by coordinate transformation.)
