Abstract :
A method to design stabilizing controllers for a class of discrete time varying systems with bounded time variance is presented in this contribution. It uses the guaranteed cost concept to assess the system´s performance and the direct method of Lyapunov for stability considerations. Thus it resorts to techniques already known for uncertain systems. The controller determined using this method is given in terms of the solution to one of two modified Riccati equations
