Abstract

This paper presents the degradation of the system performance according to the vmiation of the rotor time constant. The algorithm for the on-line estimation of rotor time constant is proposed. which is applied to the consistent relationship between the tangent torque angle of the synchronous reference frame and that of stationary reference f frame. For the purpose of the validity of proposed algorithm. the computer simulation and the experiments have been p performed.

본 논문에서 회전자 시정수 변화에 따른 벡터제어 시스템의 성능저하에 대하여 고찰하고, 동기좌표계의 탄젠트 토크각과 정지좌표계의 탄젠트 토크각의 일치 관계를 이용하여 온라인으로 회전자 시정수의 변화를 추정하는 알고리즘을 제안한다. 제안한 알고리즘의 타당성을 검토하기 위하여 컴퓨터 시뮬레이션 및 실험을 수행하였다.
