| Abstract: | A method of estimating the rotor position and speed based on extended Kalman filter(EKF) for permanent magnet synchronous motor(PMSM) is proposed.A scheme of sensorless drive of PMSM can be realized by using this method.By using monitoring stator voltages and currents,it is possible to estimate the rotor position and speed and implement PMSM drives without position and speed sensors.Simulation and experimental results show the feasibility and effectiveness of this algorithm. |
