| Abstract: | To improve the performance of sensorless direct torque control of permanent magnet synchronous motor,a method integrating extended Kalman filter and sliding mode observer for PMSM speed and position estimation is proposed in this paper.And Matlab/Simulink is used to establish the speed control system used sensorless direct torque control method,and achieve the simulatioin of jump-start and speed control.The simulation results show that the method has more satisfactory performance. |
