Abstract

This paper proposes a new starting and low speed control method of sensorless control for permanent synchronous motor (PMSM) based on high frequency rotating voltage signal injection. This method can control the motor starting from standstill and running in low speed no need to distinguish the polarity of the rotor. The method include two rotor position estimating mode: open-loop estimating mode using in starting up status, and the closed-loop estimating mode using in low speed running status. The traditional sensorless drive scheme using high frequency rotating voltage injection can estimate the position of the rotor but can not distinguish the polarity, so the extra complex algorithm to distinguish the rotor position is often required. The proposed open-loop estimating mode of rotor position can solve this problem. When the rotor starting from standstill, if the estimated polarity of the rotor is not the truth, the pole N of the rotor can automatically adjust to the estimated position through a initial and short reverse rotation. This method based on saliency of the rotor but has no sensitivity to the armature resistance and inductance. The experiment results show the feasibility and effectiveness of the proposed method in a wide speed range including standstill.
