Observer-based dynamic event-triggered consensus tracking of multi-agent systems under DoS attacks with external disturbances

This paper explores the issue of dynamic event-triggered consensus tracking in linear multi-agent systems (MASs) with directed topology and external disturbances, especially in the presence of DoS attacks. An observer-based event-triggered resilient controller and a dynamic event-triggering mechanism are presented to address the consensus tracking. By leveraging the proposed dynamic event-triggered control strategy, continuous communication among neighboring agents and full-state information is unnecessary, ensuring the guarantee of leader-following consensus. Additionally, the adoption of the dynamic event-triggering mechanism prevents MASs from exhibiting Zeno behavior in presence of disturbances and reduces triggering instances compared to the static event-triggering mechanism. Finally, case studies are conducted to demonstrate the effectiveness of the proposed approaches.
