Non‐Fragile Secure Consensus Control of Second‐Order Multiagent Systems Under DoS Attacks

ABSTRACT

This article investigates non‐fragile secure consensus control of second‐order linear/nonlinear multiagent systems under denial‐of‐service attacks. When both uncertainties and denial‐of‐service attacks exist in the communication networks at the same time, distributed non‐fragile secure consensus algorithms are designed to realize the consensus, and model‐based Lyapunov functions combined with the average dwell‐time method are employed for the subsequent stability analysis. Sufficient conditions guaranteeing the asymptotic consensus of the systems are developed in light of the controller parameters, duration, and frequency of the attacks. The control performance is further considered in the existence of the external disturbances. Numerical simulations are provided to demonstrate that the secure consensus can be reached effectively under the proposed control mechanism.
