چکیده
Abstract: This paper considers the problem of robust mixed 2 H / ∞ H delayed state feedback control for a class of uncertain neutral systems with time-varying discrete and distributed delays. Based on the Lyapunov-Krasovskii functional theory, new required sufficient conditions are established in terms of delay-range-dependent linear matrix inequalities (LMIs) for the stability and stabilization of the considered system using some free matrices. The desired robust mixed 2 H / ∞ H delayed control is derived based on a convex optimization method such that the resulting closed-loop system is asymptotically stable and satisfies 2 H performance with a guaranteed cost and a prescribed level of ∞ H performance, simultaneously. Finally, a numerical example is given to illustrate the effectiveness of our approach.

This paper presents H∞ control problem for input-delayed systems. A neutral system approach is considered to the design of PD controller for input delay systems in presence of uncertain time-invariant delay.
