摘要：

The problem of the delay-dependent non-fragile H(infinity) observer-based control for a class of continuous time-delay systems is investigated in this paper. The additive gain variations under consideration are contained in both the controller gain and observer gain. Delay-dependent criteria are derived to guarantee the stability of the non-fragile H(infinity) observer-based control system using the Lyapunov functional approach. The controller and observer gains are given from the LMI feasible solutions. Based on the result of this paper, the constraint of matrix equality is not necessary for designing the non-fragile H(infinity) observer-based controls. Computer software Matlab can be applied to solve all the proposed results. Finally, a numerical example is illustrated to show the improvement of this paper. (C) 2008 Elsevier Inc.
