Abstract

A fast maximum efficiency control scheme of a stator flux-oriented control of an induction motor is proposed. Three inputs of given three magnetic fluxes are calculated. Then magnetic flux for minimum input is calculated by quadratic interpolation method and maximum efficiency control is fulfilled with the calculated magnetic flux for minimum input. Simulation results verify the effectiveness of the scheme.

유도전동기 고정자자속 기준제어의 최대효율제어를 위한 초기자속 값의 계산방법을 제안한다. 3개의 자속에 대한 입력을 계산한 후 3점을 2차 보간하여 2차 함수의 최소점, 즉 입력이 최소가 되는 자속을 구하고, 이 자속을 초기 값으로 하여 최대효율제어를 수행한다. 시뮬레이션 결과 기존의 방법에 비해서 제안한 방법에 의하여 최대효율점으로의 수렴시간이 단축됨을 보인다.
