N2 - In this paper, a switched robust control is designed for a class of discrete-time systems subject to linear fractional uncertainty and interval time-delays. The controller is based on state feedback and the LMIs-based stability conditions are derived using an improved Lyapunov-Krasovskii functional. Moreover, the switching rule as well as the state feedback gains are determined from the minimisation of a guaranteed cost function. The theoretical results are illustrated with numerical examples.
