In this work, using Lyapunov-Krasovskii functionals, a less conservative lower bound for the dwell time is obtained. Improvement in the dwell time is illustrated with an example. © 2011 IFAC.EnglishLyapunov methodsSwitched systemsTime delayDwell timeLower boundsLyapunov-Krasovskii functionalsLyapunov-Razumikhin functionsPiece-wiseStability analysisSwitched systemTime-delay systemsLyapunov functionsLyapunov methodsTime delaySwitching systemsConference Paper10.3182/20110828-6-IT-1002.00064
