Abstract

In this paper, numerical stability analysis methodology for the singleton-type linguistic fuzzy control systems is proposed. The proposed stability analysis is not the analytical method but the numerical method using the convex optimization of Quadratic Programming (QP) and Linear Matrix Inequalities (LMI). Finally, the applicability of the suggested methodology is highlighted via simulation results.

본 논문에서는 새로운 방식의 싱글톤 형태 퍼지 제어기의 안정도 해석 방식을 제안한다. 본 논문에서 제안되는 방식은 기존의 논문에서 찾을 수 있는 해석적 방식이 아니라 최적화 알고리즘을 이용한 수치적 접근 방식이다. 본 알고리즘은 크게 이차계획법과 선형 행렬 부등식으로 이루어져 있다. 끝으로 컴퓨터 모의 실험을 통해 타당성을 확인한다.
