초록

본 논문은 이산시간 상호결합 퍼지 시스템을 위한 관측기 기반 분산 퍼지 제어기 설계 기법을 연구한다. 이를 위해 먼저 상호결합 퍼지 시스템의 퍼지 하위시스템을 고려하고, 이를 바탕으로 관측기 기반 분산 퍼지 제어기를 설계한다. 그리고 퍼지 하위시스템과 관측기 기반 분산 퍼지 제어기를 이용하여 폐루프 시스템을 구한다. 구해진 폐루프 시스템에 대해 최대 상호결합 범위를 포함한 안정도 조건을 도출하고, 이를 선형 행렬 부등식 형태로 나타낸다. 마지막으로 모의실험을 통해 제안된 제어기 설계 기법의 타당성을 분석한다.

In this paper, an observer-based decentralized fuzzy controller is designed for discrete-time interconnected fuzzy systems. Based on the fuzzy subsystem of the interconnected fuzzy system, the observer-based decentralized fuzzy controller is considered. By using the fuzzy subsystem and the observer-based decentralized fuzzy controller, the closed-loop system is obtained. From the closed-loop system, the stability condition with the maximum interconnection bound is developed, and its sufficient condition is represented as the linear matrix inequality (LMI). Finally, the numerical example is provided to verify the effectiveness of the proposed technique.
