This　paper　addresses　the　issue　of　decentralized　adaptive　event-triggered　fault-tolerant　synchronization　tracking　control　for　multiple　unmanned　aerial　vehicles　(UAVs)　and　unmanned　ground　vehicles　(UGVs)　with　prescribed　performance　subject　to　actuator　faults　and　external　disturbances.　The　transformed　error　is　presented　by　integrating　the　prescribed　performance　function　into　the　synchronous　tracking　errors.　Based　on　the　transformed　error,　the　decentralized　adaptive　event-triggered　fault-tolerant　synchronization　tracking　control　scheme　is　developed　to　achieve　the　synchronous　tracking　purpose　with　prescribed　performance　subject　to　actuator　faults　and　external　disturbances.　Based　on　Lyapunov　theory,　the　stability　of　the　closed-loop　systems　is　analyzed　and　the　synchronous　tracking　errors　are　bounded　within　the　prescribed　boundary.　Furthermore,　the　Zeno　behavior　is　also　excluded.　Finally,　simulation　studies　are　provided　to　verify　the　efficiency　of　the　proposed　control　scheme.
