Abstract
Recently, permanent magnet synchronous motor (PMSM) drive systems without the rotor position sensor are widely used as actuators in many applications. However, in the case of a pulsating load such as the compressors, the rotational speed of the motors is fluctuated and the drive system is vibrated due to the pulsating load torque. In this paper, we propose a new method to reduce the rotational speed pulsation. This method can seamlessly change the vibration suppression control and the high efficiency control. The simulation results indicate that the proposed method is very effective and practical.Keywords
