Abstract

In this paper, distributed tension observer for R2R process is proposed. The minimal order observer theory is utilized to design the distributed tension observer. The proposed method estimates the tension of a specific sub-process based on the speed and tension information from its adjacent sub-processes. Utilizing its properties, the proposed method can be applied to decentralized control structure. In order to achieve high estimation accuracy, sliding mode technique is also adopted to the proposed method.

본 논문에서는 롤투롤 프린팅 공정을 위한 분산 처리 장력 관측 방법을 제안한다. 제안된 분산 처리 장력 관측기는 최소 차수 관측기 이론을 이용하여 설계된다. 제안된 방법은 인접 공정 영역의 속도와 장력 정보를 바탕으로 해당 공정 영역의 장력을 관측하는 특성을 가지고 있어 분산 제어 구조에 사용이 가능하다. 또한 제안된 방법은 슬라이딩 모드를 채용하여 모델 변동에 대해서도 효과적인 추정 성능을 갖는다.
