H∞ control for T-S fuzzy neutral systems with time-varying delays and actuator saturation

This paper studies the H_∞ control problem for a class of Takagi-Sugeno (T-S) fuzzy neutral systems with time-varying delays and actuator saturation, where the delay in neutral-type term includes a fast-varying case (i.e., the derivative of delay is more than 1), which is never considered in current literature for this systems. The new LMI-based delay-dependent H_∞ control results for this systems are proposed by applying a new Lyapunov-Krasovskii functional and the auxiliary feedback matrix method. Based on the new functional, the fuzzy systems with fast-varying neutral-type delay can be considered. A numerical example is provided to verify the effectiveness of the proposed results.
