A Study on Improvement of Low Speed Control Characteristics in PMSM

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.
