Dynamic event-triggered prescribed time bipartite consensus for matrix-weighted HMASs under asynchronous attacks

This article is centered on event-triggered prescribed-time bipartite output consensus issue for matrix-weighted heterogeneous multi-agent systems under asynchronous DoS attacks, where the dependencies between adjacent agents are characterized by the matrix weights of the edges within the network. First, the system suffering from invalid attack is considered as a switching system. Then, by limiting the duration of the valid attack, a novel prescribed-time bipartite compensator with a static event-triggered mechanism is introduced to track the leader's state for this category of generalized networks. In order to reduce communication between agents to a greater extent, we introduce a prescribed-time bipartite compensator with a dynamic event-triggered mechanism. Moreover, we demonstrate that neither mechanism exhibits Zeno behavior. Then, through compensator, a distributed state-feedback control protocol and an output-feedback control protocol are designed to achieve prescribed-time bipartite output consensus. Finally, simulation examples are presented to validate the validity of the main results.
