Comparative Analysis of PI Controller and Disturbance Cancellation Observer of a Feedforward

비례적분제어기와 feedforward 외란상쇄 관측기의 비교분석

Abstract

This paper designed a robust control of an induction motor using a disturbance cancellation observer of a feedforward control. The speed response of conventional PI controller characteristic is affected by variations of load torque disturbance. In the proposed system, the speed control characteristic used a feedforward control which does not undergo the influence of the load torque disturbance. High speed calculation and processing for vector control is carried out by TMS320C31 digital signal processor. Validity of the proposed control method is verified through simulation and experimental result.

이 논문은 피드포워드 왜란상쇄 관측기를 이용하여 유도전동기의 강인한 제어를 얻을 수 있었다. 전통적인 비례적분 제어기의 속도응답 특징은 부하 토크 요소의 변이에 영향을 받는다. 제안한 시스템에서 속도제어 특성은 부하토크 외란에 영향을 받지 않는 피드포워드 제어를 사용하였다. 벡터제어를 위한 높은 속도의 계산과 처리를 위해 TMS320C31 디지털 프로세서를 사용하였다. 제안한 제어 방법의 타당성을 입증하기 위해 시뮬레이션과 실험을 통해 확인하였다.
