초록

Sensorless PMSM is much studied for the industrial applications and home appliances because a mechanical sensor reduce reliability and increases cost. Most of sensorless algorithm have poor performances in a low speed range. This paper investigates Performance improvement in a low speed range of PMSM. The proposed control scheme is based on the optimization of ratio between the command and dc-link voltages. The experiment is performed in this study. and the result shows the improved Performance in a low speed range.
