Abstract

In this paper, an adaptive input-output linearization and zero dynamics control of three phase AC/DC converter are proposed. For achieving output do voltage regulation with unity power factor, the q-axis current of the rotating d-q frame is regulated to zero and the output do voltage is controlled to track a given reference voltage $V_r$. The proposed scheme is robust to the parametric uncertainty md load current of the converter due to the adaptation process. The simulation results are presented to illustrate the performance and feasibility of the proposed control scheme.

본 논문에서는 3상 AC/DC 컨버터의 적응 입출력 선형화와 영점 동특성식 제어 기법을 제안한다. 컨버터 출력 dc전압이 단위 역률을 유지하도록 회전 d-q 프레임의 q축 전류가 영의 값으로 유지되고 출력전압은 주어진 기준전압 $V_r$을 추종하도록 제어된다. 제안된 제어기법은 적응 프로세스를 이용해 파라미터 불확실성과 부하 전류 변화에 대해 견실하다. 제안된 제어 기법의 효용성과 타당성을 보이기 위해 시뮬레이션 연구가 수행되었다.
