This　article　investigates　the　resilient　output　synchronization　problem　of　a　class　of　linear　heterogeneous　multiagent　systems　subjected　to　denial-of-service　(DoS)　attacks.　Two　types　of　control　mechanisms,　namely,　event-　and　self-triggered　control　mechanisms,　are　presented　so　as　to　cut　down　unnecessary　information　transmission.　Both　of　these　two　mechanisms　are　distributed,　and　thus,　only　local　information　of　each　agent　and　its　neighboring　agents　is　adopted　for　the　event　condition　design.　The　DoS　attacks　are　considered　to　be　aperiodic,　and　the　quantitative　relationship　between　the　attributes　of　the　DoS　attacks　and　the　synchronization　is　also　revealed.　It　is　shown　that　the　output　synchronization　can　be　achieved　exponentially　in　the　presence　of　DoS　attacks　under　the　proposed　control　mechanisms.　The　validness　of　the　provided　mechanisms　is　certified　by　a　simulation　example.
