Abstract

A improved current controller with reference modification part that has both fast transient response in transient state and high accuracy in steady state is proposed. In this scheme, a improved reference modification part is used to synchronous frame PI controller for the fast transient state. The transient response of current controller is seriously deteriorated in high back e.m.f.(electromotive force) due to the lack of DC link control voltage. This paper is proposed that the improved reference modification part is compared with voltage limit and reference voltage.

개선된 지령치 변경부를 가지는 전류제어기는 과도 상태에서의 빠른 응답성과 정상 상태에서의 고정밀도를 가진다. 이 논문에서는 개선된 지령치 변경부가 빠른 과도 응답성을 위하여 동기 PI 제어기를 사용하였다. 전류 제어기의 과도 응답특성은 DC 링크 제어 전압의 부족으로 인해 높은 역기전력 영역에서 많은 문제를 가지고 있다. 이 논문은 지령 전압과 한계 전압을 가지는 개선된 지령치 변경부를 제안하였다.
