Abstract：To address the practical finite-time bipartite consensus problem of general linear multi-agent systems where the agents' state information is not fully accessible and communication resources are limited,a Luenberger observer is introduced by adopting output feedback approach,and a distributed dynamic event-triggered finite-time bipartite consensus protocol is designed based on the estimated observer state.This protocol takes into account the coexistence of cooperative and competitive relationships in the network topology,effectively overcoming the limitations of agent state measurement in practical applications and significantly reducing the communication frequency of the system.Meanwhile,utilizing finite-time stability theory,algebraic graph theory,and matrix theory,sufficient conditions are derived under which the multi-agent system can achieve practical finite-time bipartite consensus with the designed control protocol,and it is proven that the system is free from Zeno behavior.By constructing a dynamic event-triggered mechanism that matches the finite-time bi-partite consensus control,the proposed control algorithm exhibits satisfactory advantages in saving system communication resources.Finally,the feasibility and effectiveness of the theoretical results are verified through simulation examples.
