Delay-dependent robust output-feedback control for time-delay uncertain systems

This paper addresses the problem of delay-dependent robust stabilization for a class of uncertain time-delay systems via using memoryless output feedback controller. The uncertainty in the system is assumed to be norm-bounded and time-varying. The time-delay occurs both in the state equation and measurement equation of the system. There exits a memoryless output-feedback controller, if four matrix inequalities are feasible. In an example, the approach of this paper is applied to a particular system in order to show that the results are effective.
