영구자석형 동기전동기의 저속도 제어 특성 개선에 관한 연구

This paper presents the method of speed measurement for permanent magnet synchronous motor(PMSM) with the full-order observer using reduced-order state equation This is able to improve the operating performance at low speed Therefore, by the proposed technique, a low resolution encoder can be used. Because It make the system Improve the performance of speed response. The proposed method is verified to simulation and experiments
