Abstract
피제어 공정 변수의 추적 제어와 함께 최종 생산물 품질을 예측치에 근거하여 실시간에서 제어하는 회분/반회분 공정의 새로운 모델 예측 제어 기법을 제안하였다. 제안된 제어 기법은 회분 단위의 되먹 임 기능을 통해 상당한 모델 오차가 존재하는 경우에도 회분이 반복되며 제어 오차가 영으로 수렴하는 성능을 가진다. 회분 및 반회분 반응기 모델에서의 수치 모사를 통해 본 연구에서 제안한 제어기의 성능을 검증하였다.
In this study, we propose a model predictive control technique for batch and semi-batch processes which can conduct prediction-based control of final product quality together with tracking variables. The proposed control technique can dwindle the tracking as well as quality control error to zero by feeding back the previous batch information to the current batch. Performance of the proposed control technique has been demonstrated through numerical simulation with batch and semi-batch reactors.
