Abstract

In order to achieve the speedsensorless control for permanent magnet synchronous motor(PMSM), this paper proposed a speed control strategy of PMSM based on the integral proportion (IP) controller and the extended Kalman filter (EKF). Considering the stator voltage and current in αβ reference frame as inputed, the rotor speed and position were online predicted and optimally estimated by using the EKF algorithm. The error between the desired and the estimated speed was defined as the input of the IP controller to control the current component of q rotating reference frame, so that the speed-sensorless control of the PMSM could be achieved. Comprehensive simulation results on different motor speed and load conditions demonstrate that the proposed control strategy possess strong disturbance rejection ability and small overshoot.

Key words： permanent magnet synchronous motor(PMSM); speed-sensorless control; extend Kalman filter (EKF); integral proportion (IP) control
