Abstract

This paper proposes a robust digital speed regulator for a surface-mounted permanent magnet synchronous motor(SPMSM). The proposed speed controller uses a simple digital load disturbance resistance scheme which does not require a load torque observer, so it can be easily and simply implemented without degrading the control performance. To validate the effectiveness of the proposed control algorithm, experimental results as well as simulation results are shown under motor parameter variations using a prototype SPMSM driving system. Finally, it was confirmed that the proposed method can precisely regulate the speed of the SPMSM.

본 논문에서는 표면부착형 영구자석 동기전동기를 위하여 강인한 디지털 속도제어기를 제안한다. 제안된 속도제어기는 부하 토크관측기를 필요로 하지 않는 간단하며 부하 외란에 둔감한 디지털 제어 기법을 사용하므로 제어성능의 저하 없이 쉽고 단순하게 구현될 수 있다. 제안된 제어 알고리즘의 성능을 검증하기 위하여, 프로토타입 표면부착형 영구자석 구동시스템을 이용하여 시뮬레이션 및 실험을 하였다. 모터 파라미터 변동 하에서 수행된 시뮬레이션 및 실험결과를 통하여 제안된 기법이 표면부착형 영구자석 동기전동기의 속도를 정확하게 제어할 수 있음을 확인하였다.
