STATIC OUTPUT FEEDBACK ROBUST CONTROL OF UNCERTAIN LINEAR DISCRETE-TIME SYSTEMS

Danica Rosinová - Vojtech Veselý

   The output feedback robust stabilization problem is studied in this paper for uncertain discrete-time linear system described in state space using polytopic model. The necessary and sufficient conditions for output feedback stabilizability with guaranteed cost are provided as well as the algorithm for computation of output feedback gain matrix. The LMI formulation enables to employ standard efficient computational tools (MATLAB).

Keywords: discrete-time systems, output feedback, quadratic stabilization, Riccati equations, LMI approach
