碩士 === 義守大學 === 電機工程學系碩士班 === 94 === In this dissertation, the robust H∞ control for Takagi-Sugeno fuzzy systems with time-varying state and input delays is considered. New Lyapunov-Krasovskii functional theory and Leibniz-Newton formula are used to solve the robust H∞ control problem. Delay-dependent stabilizability criteria are proposed to achieve the H∞ controls for two classes of fuzzy systems with parametric and nonlinear uncertainties, respectively. LMI optimization approach is applied to solve the H∞ control problem. The minimization of H∞ norm bound is found from LMI formulation. From the simulation results of the proposed methods in this dissertation, significant improvement over the recent results can be observed.
