This　article　studies　the　finite-time　consensus　control　of　a　multi-agent　system,　and　the　trigger　method　adopts　event　trigger.　A　finite　time　controller　that　uses　first-order　neighbor　information　and　second-order　neighbor　information　to　trigger　events　is　designed.　It　was　subsequently　proved　that　the　system　can　reach　a　consensus　within　a　limited　time　under　the　event-triggered　control　protocol,　and　at　the　same　time　eliminate　Zeno　behavior　through　periodic　sampling.　The　application　of　second-order　neighbor　information　speeds　up　the　convergence　speed　of　the　system.　In　addition,　the　introduction　of　the　state　combination　measurement　method　can　advantageously　reduce　the　number　of　controller　updates.　Finally,　a　case　is　given　to　explain　the　validity　of　the　proposed　theory.　©　2022,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Singapore　Pte　Ltd.
