This　paper　considers　the　dichotomy　of　nonlinear　interconnected　systems　with　uncertainties.　This　class　of　nonlinear　interconnected　systems　not　only　exist　linear　connections　in　states,　but　also　achieve　the　input　and　output　interconnections　through　a　per-mutation　matrix.　Linear　matrix　inequality　(LMI)　conditions　of　dichotomy　of　nonlinear　interconnected　systems　with　uncertainties　are　derived.　A　method　of　controller　design　and　the　sufficient　condition　of　dichotomy　of　the　nonlinear　interconnected　systems　are　given.　Numerical　example　are　given　to　illustrate　the　effectiveness　of　the　proposed　methods.
