Fully distributed adaptive dynamic event-triggered secure consensus of lipschitz nonlinear multiagent systems under DoS attacks

Abstract

This work discusses the secure consensus issue of Lipschitz nonlinear multiagent systems (MASs) subject to denial-of-service (DoS) attacks. Due to the presence of DoS attacks, a new update rule for adaptive parameters has been designed. Meanwhile, a novel event-triggered (ET) strategy with an auxiliary dynamic variable is presented to cut down unnecessary communication, save energy and prolong the network lifetime. And the corresponding control strategy is developed and does not need to use any global information. Moreover, a well designed Lyapunov function is introduced for stability analysis. The sufficient criteria for achieving consensus convergence have been derived, and the Zeno phenomenon has also been avoided, where the relation between attack constraints, system matrix and triggering parameters has been clarified. Finally, the feasibility and validity of the designed ET control strategy are validated through a simulation experiment.
