Abstract

This paper focuses on H_∞ control design problem for T-S fuzzy time-delay systems with actuator saturation. Based on Lyapunov-Krasovskii Functional (LKF) combining the introduction of relaxed matrices, a H_∞ controller design method is presented in Linear matrix inequality (LMI) forma. The controller designed is capable to reject the disturbance assumed known and norm bounded. A numerical example is provided to verify the effectiveness of the proposed results.
