Non-Fragile Hinfinity Observer-Based Control for Continuous Time-Delay Uncertain Systems

This paper investigates the observer-based controls for a class of continuous time-delay uncertain systems . System states contain some uncertain elements.The additive gain variations under consideration are contained in both the controller gain and observer gain. 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∞ observer-based controls. Matlab can be applied to solve all the proposed results. Finally,a numerical example is illustrated to show the improvement of this paper.
