Edge-based adaptive secure consensus for nonlinear multiagent systems with communication link attacks

Fully distributed secure consensus control of nonlinear multiagent systems under communication link attacks is achieved, where the design criteria are independent of the Laplacian matrix related to the communication topology and its corresponding eigenvalues. Firstly, this article proposes an edge-based fully distributed adaptive protocol for leaderless nonlinear multiagent systems with communication link attacks to achieve secure consensus control, where the interaction strengths between neighboring agents are adaptively adjusted on the foundation of the transmitted relative states to counteract influences of communication link attacks. Then, the problem of secure consensus control for leaderless nonlinear multiagent systems with communication link attacks is transformed into the stability of secure consensus error systems, and sufficient conditions for leaderless nonlinear multiagent systems achieving fully distributed secure consensus control are given. Furthermore, main results for leaderless nonlinear multiagent systems are extended to leader-following cases. Finally, theoretical results are verified by two numerical examples.
