Abstract

This paper proposed a non-filter position sensorless control (PSC) for the permanent-magnet synchronous motor (PMSM), which is based on an a-ß frame complex PI controller. The chattering of estimated Back-EMFs is unavoidable with a sliding mode PSC. A low pass filter (LPF) is always employed to smooth Back-EMFs; however phase lag of LPF becomes significant as motor speed increases. A complex PI controller is proposed to estimate back-EMFs without LPFs. The proposed method is implemented by replacing SMC and cascaded LPFs with a single complex PI controller, therefore complexities of proposed PSC have not been increased. Experiments were carried out on a PMSM drive to confirm the advantages of the proposed method over sliding mode PSC.
