In　this　article,　we　study　the　issue　of　adaptive　neural　output-feedback　controller　design　for　a　class　of　uncertain　switched　time-delay　nonlinear　systems　with　nonlower　triangular　structure.　The　prominent　contribution　of　this　article　is　that　the　delay-dependent　stability　criterion　of　nonswitched　nonlinear　systems　is　successfully　extended　to　that　of　switched　nonlower　triangular　nonlinear　systems.　The　design　algorithm　is　listed　as　follows.　First,　a　switched　state　observer　is　designed　such　that　the　error　dynamic　system　can　be　generated.　Second,　neural　networks,　adaptive　backstepping　technique,　and　variable　separation　method　are,　respectively,　applied　to　construct　a　common　controller　for　all　subsystems,　in　which　the　Lyapunov-Krasovskii　functionals　are　deliberately　constructed　such　that　the　average　dwell-time　scheme　can　be　employed　to　guarantee　the　stability　and　performance　of　the　closed-loop　system,　despite　the　existence　of　time　delays.　Third,　the　stability　analysis　process　confirms　in　detail　that　all　the　variables　of　the　closed-loop　system　are　semiglobally　uniformly　ultimately　bounded.　Finally,　simulation　study　is　given　to　show　the　validity　of　the　proposed　control　approach.
