Abstract: Explores the problem of the robust guaranteed cost control with quadratic stability of uncertain discrete-time switched systems under arbitrary switching laws, based on LMIs. Constructing LMIs using Schur complement lemma, several sufficient conditions are given in terms of LMIs for the problem. With these less conservative conditions the quadratic stability are easy to check and the upper bound of cost index can be satisfied. The effectiveness of the method has been illustrated by a numerical example.
