Abstract :
This paper focuses on guaranteed cost output feedback control of linear time-varying uncertain discrete systems. A dynamic output feedback compensator is presented to ensure not only the stabilization of a plant with norm-bounded uncertainty but also some desired performance. The sufficient conditions for the existence of the dynamic output feedback compensator are derived. An equivalent linear time-invariant discrete H∞ output feedback structural description for time-varying uncertain discrete systems is obtained to construct dynamic output feedback compensator
