초록

본 논문은 이산시간 비선형 상호결합 시스템에 대한 지능형 분산 관측기 설계 기법을 제안한다. 여기서, 비선형 상호결합 시스템은 미지의 상호결합을 갖는다고 가정한다. 설계하는 지능형 분산 관측기 설계를 위한 문제를 설정하고, 문제를 해결할 수 있도록, 성능함수를 정의한다. 정의된 성능함수를 기반으로, 지능형 분산 관측기 설계 문제를 해결할 수 있는 충분조건을 구하고, 이를 선형 행렬 부등식의 형태로 나타낸다. 마지막으로 모의실험을 통해 제안된 지능형 분산 관측 기법의 성능을 확인한다.

In this paper, the decentralized fuzzy observer design technique is presented for discrete-time nonlinear interconnected systems, which are assumed to be with unknown interconnections. To design the decentralized fuzzy observer, the design problem is considered and the performance function is defined to solve the design problem. Based on the performance function, the sufficient condition is derived for the observer design, and its condition is formulated into linear matrix inequalities. Finally, by the simulation result, the validity of the proposed observer design technique is shown.
