초록

본 논문에서는 컴퓨터 연산을 통한 언어형 퍼지 제어 시스템의 안정도를 해석하는 새로운 방법을 제안한다. 제안하는 방법은 최근 각광을 받고 있는 선형행렬부등식을 이용한 방법이다. 기존의 수치적 방법과 비교할 때 본 논문에서 제안되는 방식의 특징은 좀더 완화된 방식으로 안정화 문제뿐 아니라 고정점 레귤레이션 문제에도 적용될 수 있는 특징을 가지고 있다. 끝으로 컴퓨터 모의 실험을 통하여 제안한 방법의 타당성을 확인한다.

In this paper, a novel computational approach for the stability analysis of the linguistic fuzzy system is proposed. The suggested analysis method is easily implemented by the recently spotlighted convex optimization techniques called Linear Matrix Inequalities (LMI). Compared with the previous works, the new method proposed herein is more relaxed and is applicable to not only the stabilization problem but also to the set-point regulation problem. Finally, the applicability of the suggested methodology is highlighted via computer simulations.
