摘要
本文根据定子磁场定向理论,介绍了一种直接转矩控制的方法,通过动态计算电机定子端的电压矢量,实现了对异步电机的解耦控制,较矢量控制方法具有更优的控制性能,包括磁链幅值控制与转矩控制性能都得到很大的提高,试验结果证明了本文所叙方法是有效的。
On the basis of the stator flux oriented control theory,a method of the direct torque control is presented in this paper.The decoupled control for pulse width modulation inverter fed induction motor is realized by dynamic calculation of the induction motor stator voltage vector.The proposed method has better performance in torque and magnetic field than vector control.The test's result demonstrates the proposed method is correct and effective.
