DoS攻击下二阶多智能体系统二分跟踪一致性

Bipartite Consensus Tracking of Second-Order Multi-Agent Systems Under DoS Attacks

针对拒绝服务(denial-of-service,DoS)攻击下的二阶非线性多智能体系统,研究了其领导跟随安全二分一致性问题。所考虑的DoS攻击是基于时间序列且非周期发生的攻击。针对无时滞和有通信时滞两种情形,分别设计了分布式二分一致性协议,利用李雅普诺夫稳定性理论和图论,分析了二分误差系统的稳定性,得到了多智能体系统实现二分跟踪一致性与DoS攻击频率、长度比率及控制参数等相关的充分条件。通过仿真实例验证了所设计方法的正确性。

The leader-following secure bipartite consensus problem is investigated for second-order nonlinear multi-agent systems under denial-of-service(DoS)attacks.A class of aperiodic DoS attacks based on time series is considered.Distributed bipartite consensus protocols are designed for multi-agent systems without and with communication delay,respectively.Lyapunov stability theory and graph theory are utilized to analyze the stability of bipartite error systems.Sufficient conditions are derived for ensuring the leader-following bipartite consensus of multi-agent systems,which involve the attack frequency,the length rate of DoS attacks,control parameters and so on.Finally,simulation examples demonstrate the correctness of the designed method.
