Abstract

Position information is very important when driving the Permanent Magnet Synchronous Motor(PMSM). Generally, resolver is used to obtain exact position information. However, it generates periodic position errors due to the transformer ratio difference and excitation signal distortion. When the vector control is done with the position information that includes position error, torque ripple is generated from time to time. This paper proposes the solution through analysis of above problem. Also, it's validity is verified by simulation and experiment.

영구자석형 동기전동기(Permanent Magnet Synchronous Motor, 이하 PMSM)의 벡터제어 시 회전자의 위치 정보는 매우 중요하며, 최근 레졸버를 이용하여 센싱하는 응용분야가 늘어나고 있다. 레졸버의 턴수비 차이나 불평형 여자신호로 인하여 회전자의 위치각 정보가 왜곡되며, 이는 벡터제어 시 출력측 토오크 리플로 나타나는 문제점이 있다. 이러한 문제점을 이론적으로 분석하였고, 이에 대한 전류보상 알고리즘을 제안하였다. 또한 시뮬레이션과 시험을 통하여 타당성 및 유효성을 검증하였다.
