| Abstract: | This paper presents an improved flux MRAS-based identification method and applied to direct torque control system, can greatly improve system performance in the large speed range. Paper uses the fuzzy speed controller instead of the traditional PI speed controller to reduce the PI parameters of the dependence on the system parameters to improve the performance of the whole control system. Simulation results show that the proposed method achieved good control effect. |
