초록

본 논문은 대규모 연속시간 T-S (Takagi-Sugeno) 퍼지 시스템의 고장검출을 위한 관측기 설계 문제를 논의한다. 관측기의 출력신호로부터 고장 여부를 판단하기 위해서 관측기는 고장신호에 가능한 민감해야하며 이를 위해 $\mathfrak{H}_-$ 성능지수를 도입한다. 설계 조건은 선형행렬부등식으로 표현되며 수치적 예제로부터 그 효용성을 확인한다.

In this paper, we discuss a decentralized observer design problem for the fault detection in the large-scale continuous-time T-S (Takagi-Sugeno) fuzzy system. Since the fault detection residual is desired to be as sensitive as possible, on the fault, we use $\mathfrak{H}_-$ index performance criterion. Sufficient conditions for the existence of such a observer is presented in terms of linear matrix inequalities. Simulation results show the effectiveness of the proposed method.
