摘要
提出了异步电动机定子,转子磁链观测方法,利用u-i模型定子磁链观测方法,并且在转子磁链的基础上估算出电机的转速,这种观测方法能够提高速度观测精度,定子磁链观测与速度观测相结合应用到直接转矩控制系统中,能使直接转矩控制系统的低速性能得到较大提高。
Proposed the asynchronous motor stator, the asynchronous motor flux observation method, uses the u-i model stator flux observation method, and Based on the flux observers, a novel speed estimator is designed., The simulation and experiment results show that these methods can improve the accuracy of the observed speed, the stator flux bservation and the speed observation unifies applies in the direct torque control system, can enable the direct torque control system the low-speed performance to obtain enhances greatly.
