Abstract
For sensorless control, the rotor position estimation performance is affected by the load change. In order to solve this problem, this paper proposes a position error compensation method based on the voltage output of the current-loop PI-regulator for interior permanent magnet synchronous motors. First, a traditional rotor position observer based on the rotor reference frame has been presented and it reveals that the estimated error position taken as an input of phase-locked loop is not the actual position error. Second, the relationship between the voltage output of the current-loop PI-regulator and the position error has been found out and the position error extraction model is proposed. In order to compensate the position error in the rotor reference frame, a novel position error compensation model is proposed based on the voltage and current inputs of the two-phase stationary reference frame. Finally, the proposed position error compensation method has been verified by experiments position and the estimation accuracy is improved. The results show that the position error fluctuates around zero after the compensation and the fluctuation amplitude is 1°.
