| Abstract: | 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. |
