Abstract

Abstract: This paper addresses the problem of event-triggered H ∞ control for a class of T–S fuzzy nonlinear systems. An improved event-triggered scheme (ETS) characterized by discrete sampling is proposed, where the time-derivative of the membership function is not required. To get conservative conditions, the deviation bound of asynchronous normalized membership functions is considered. By utilizing the non-quadratic fuzzy line-integral Lyapunov functions and a free-matrix-based integral inequality, novel criteria for stabilization analysis of T–S fuzzy nonlinear systems are established. Finally, a truck–trailer system is provided to show the effectiveness of the proposed theories. Abstract : Highlights: An improved discrete event-triggered scheme is proposed. Some novel criteria for stabilization analysis of T–S fuzzy nonlinear systems are established. A truck–trailer system is studied to show the effectiveness and superiority of the proposed theories.
