Abstract：

Considering　that　the　feedback　gain　is　of　additive　norm-bounded　uncertainties,　based　on　linear　matrix　inequality　(LMI),　a　design　method　of　non-fragile　guaranteed-cost　controller　for　the　networked　control　systems　(NCS)　with　network-induced　time　delay　is　discussed　in　this　paper.　A　sufficient　condition　of　such　controller　is　presented　in　LMI　forms.　The　controller　parameters　can　be　obtained　by　solving　the　LMI.　A　numerical　example　is　then　given　to　illustrate　the　effectiveness　of　the　designed　method,　that　is,　the　designed　nonfragile　guaranteed-cost　controller　ensures　the　NCS　asymptotically　stable　and　the　upper　bound　of　the　cost　function　value　in　expectation　can　also　be　obtained,　while　the　NCS　controlled　by　the　robust　guaranteed-cost　controller　will　be　unstable　with　respect　to　the　uncertainties　in　the　controller　gain.　©　2010　IEEE.
