Abstract: The switching signal design for exponential stability with H∞ performance of uncertain switched linear discrete‐time systems with interval time‐varying delay is considered. Systems with norm‐bounded parameter uncertainties are considered. By taking a new Lyapunov‐Krasovskii (LK) function, sufficient conditions for the existence of a class of stabilizing switching laws are derived in terms of linear matrix inequalities (LMIs) to guarantee the considered switched time‐delay system to be exponentially stable. The resulting stability criteria are of fewer matrix variables and are less conservative than some existing ones. In addition, numerical examples are illustrated to show the main improvement.
