通过分析异步电动机转差频率矢量控制的特点,阐述了异步电动机转差频率和同步电动机转矩角之间的本质联系。类比于异步电动机转差频率矢量控制原理,提出了同步电动机转矩角矢量控制原理。该原理适用于控制精度要求不太高的同步电动机的控制系统,具有较高的性能价格比。

By analyzing slip frequency vector control character of asynchronous motor, clarified the nature relationship between the concepts of the slip frequency of asynchronous motor and the torque angle of synchronous motor. Subsequently, the principle of torque angle vector control for synchronous motor was presented by analogy with that of slip frequency vector control for asynchronous motor. The principle of torque angle vector control for synchronous motor have higher performance-cost ratio, which is suitable for the situation that the control precision is not very high.
