Abstract

기존의 모델 예측제어기들을 단일화시킨 단일예측제어기를 다중입출력 공정으로 확장 구현하였다. 간단한 공정의 제어를 통해 구현된 다중입출력 단일예측제어기의 성능과 튜닝 파라미터의 특성을 고찰하였다. 이를 토대로 하여 쉽게 외란이 제거되고 다양한 기준궤적들을 잘 추종하는 다중입출력 단일예측제어기를 얻게 되었다. 그 결과 이러한 다중입출력 단일예측제어기로써 불안정한 비최소위상의 공정과 상호간섭이 심하고 비선형인 보일러-티빈 시스템을 효과적으로 제어할 수 있었다.
A unified predictive controller(UPC), which is the unification of various well-known predictive controllers, was extended to the multi-input multi-output(MIMO) processes. The effects of tuning parameters in the closed-loop system was studied through controlling an simple process. Based upon this study, it was found that MIMO UPC rejects disturbances more efficiently and follows the several reference trajectories as well. As a result, the unstable non-minimum process and the boiler-turbine system, which has strong interaction and nonlinearity, could be controlled efficiently by the MIMO UPC.
