Abstract:This paper is focused on the problem of robustly stabilizing linear uncertain time-de-lay systems when the full states can not be measured. The systems under consideration are linearsystems with time-varying unknown-but-bounded uncertainty and delayed state. An observerbased dynamic output feedback controller is presented to quadratically stabilize the system. A sufficient condition for the robust output feedback stabilizability of the system is derived based on Riccati equation approach and the control law can be constructed by solving two algebraic Riccatiequations. Finally,a numerical example is presented to illutrate the obtained results.
