Global　synchronization　analysis　for　complex　networks　with　coupling　delay　is　investigated　in　this　paper.　The　delay　considered　in　this　paper　is　constant.　Sufficient　conditions　depending　on　the　time　delay　are　given　based　on　Lyapunov　functional,　linear　matrix　inequality　and　Kronecker　product　technique.　The　unknown　variables　in　the　conditions　are　fewer　and　less　conservative　than　those　in　the　recent　reference.　Finally,　two　numerical　examples　are　given　to　validate　the　effectiveness　of　the　obtained　results.
