Adaptive Event-Triggered Resilient Control of Heterogeneous Multiagent Under DoS Attacks and Link Faults on Directed Graphs

This article aims to solve the event-based output consensus problem for multiagent systems on directed graphs in the presence of denial-of-service (DoS) attacks. The proposed protocol relies on a node-based self-triggered mechanism that can avoid continuous communication and the use of a strongly connected graph. This means that neither the controller nor the triggering function relies on continuous communication. By exploiting the output regulation strategy, the controller can realize output resilient consensus for linear heterogeneous multiagent systems against DoS attacks using relative observed information. This protocol offers a significant benefit in that it can be applied to directed networks without requiring the Laplacian matrix information to be taken into account. Moreover, another superiority lies in that it can handle with the situation that the communication graph contains link faults. Finally, through numerical simulations, the effectiveness of the designed protocol is demonstrated.
