In　this　paper,　the　leader-following　consensus　problem　of　multiagent　systems　with　general　dynamics　under　event-triggered　mechanisms　is　investigated.　A　centralized　event-triggered　mechanism　(CEM)　is　first　proposed.　Then,　a　distributed　dynamic　event-triggered　mechanism　is　developed　by　introducing　an　internal　variable.　In　the　CEM　case,　each　agent　uses　global　information　of　the　multiagent　system,　while　in　the　distributed　case,　each　agent　only　uses　local　information　of　its　own　and　its　neighbors.　The　multiagent　system　can　achieve　asymptotic　consensus　as　well　as　exclude　the　Zeno　phenomenon　under　the　designed　event-triggered　rules　in　both　cases.　A　multiagent　system　consisting　of　interconnected　pendulums　is　provided　to　demonstrate　the　merits　and　correctness　of　the　proposed　methods.
