구형파 2-Hall Sensor를 이용한 영구자석형 동기전동기 벡터 제어의 정역회전을 위한 회전자 위치 추정 알고리즘

This paper proposes new vector control method that using two rectangular hall sensors instead of using the expensive encoder and resolver. The proposed method is similar to T-method. But the proposed method measures the speed using two hall sensors signals instead of encoder signal. The proposed new speed estimation method is stable under the rated speed range. This algorithm will be able to moderate prices of the whole system and apply for the unfit place for use encoder and resolver.
