Abstract

This paper has proposed an algorithm for the initial pole position estimation of a permanent magnet linear synchronous motor(PMLSM). The algorithm finds the initial pole position observing the maximum values of a position generated by the new proposed two reference frames for the same force input. So, the proposed algorithm does not utilize the motor parameters and is insensitive to them. Moreover, the proposed algorithm is easily realized because the proposed method is just using PI controller

본 논문에서는 영구자석 선형동기전동기의 초기 자극위치를 추정하는 알고리즘을 제안하였다. 이 알고리즘은 전동기 파라미터를 사용하지 않고 두 제어 축에 같은 추력 지령을 인가하여 각 제어 축에 의해서 발생하는 이동거리의 최대 값을 관측하고 관측된 최대 위치 변위의 오차를 PI 제어함으로써 초기 자극 위치를 빠르고 정확하게 찾는 것이다. 제안된 알고리즘을 시뮬레이션과 실험을 통해 타당성을 검증하였다
