In this paper, the robust guaranteed cost observer-based controls for a class of uncertain time-delay systems are considered. The linear matrix inequality approach is used to design the feedback controls. Optimal guaranteed cost observer-based controls which minimize the upper bound of cost function are provided. A numerical example is given to illustrate our results.
