This　paper　is　concerned　with　dissipative　control　for　networked　stochastic　systems　with　an　event-triggered　transmission　mechanism.　Different　from　some　existing　results,　signals　from　a　physical　plant　are　sampled　non-uniformly.　In　order　to　save　precious　communication　resources,　a　data-packet　processor　is　introduced　to　choose　necessary　data-packets　based　on　a　flexible　event-triggered　condition.　By　establishing　an　integral　inequality　in　stochastic　setting,　which　is　regarded　as　a　counterpart　of　Wirtinger-based　inequality,　a　criterion　is　derived　such　that　the　resultant　closed-loop　system　is　mean-square　stable　and　dissipative.　This　criterion　is　then　used　to　calculate　suitable　event-triggered　controllers　in　terms　of　solutions　to　linear　matrix　inequalities.　An　air　vehicle　system　is　finally　taken　to　substantiate　the　validity　of　the　proposed　method.　©　2018　Elsevier　Inc.
