순시 무효전력을 이용한 영구자석 동기전동기의 센서리스 제어

초록

This paper presents a new speed sensorless control method of a permanent magnet synchronous motor based on instantaneous reactive power. The proposed algorithm is constructed by instantaneous reactive power in a synchronously rotating reference frame and is not affected by mechanical motor parameters, because mechanical equation is not used. The effectiveness of the proposed system is confirmed by the experimental results.
