| Abstract: | A nonlinear perpendicular flux observer with feedback compensation model is proposed,and combined with DTC for asyndronous motor control.The flux observer can ensure flux linkage to be perpendicular to back electromotive force,so that the stator flux linkage can be estimated accurately over a wide speed rang.The feasibility and correctness were verified by experiment results. |
