Resumo

In this paper, a switched fuzzy Lyapunov function approach is proposed to analyze the stability of continuous-time Takagi-Sugeno fuzzy systems. The results are established by exploring properties of the membership functions. The key point is that the time derivatives of the membership functions are represented as a finite polytope and less conservative linear matrix inequalities are obtained. Numerical examples illustrate the efficiency of the new stabilizing conditions. (C) 2020 Elsevier Inc. All rights reserved. (AU)
