The direct-axis or quadrature-axis stator voltage is used as manipulated variable and direct-axis or quadrature-axis stator current delay feedback is used for chaos control.
该方法以永磁同步电动机的定子交轴电压或直轴电压为控制量，利用电流的延迟反馈实现了混沌运动的控制。

The electrical drive system performance was improved using a model of the direct-axis magnetizing flux linkage space-phasor to develop a vector control scheme for the 12-phase synchronous motor.
