This article investigates the leader-following synchronization problem of multiagent systems (MASs) under hybrid cyber attacks, which refers to deception attacks and multichannel independent denial-of-service (DoS) attacks in communication channels. In order to achieve the secure control of MASs under hybrid cyber attacks, a novel impulsive control method based on topology switching is proposed, and a new algorithm for determining impulsive instants is designed. In addition, the cooperative-competitive relationship between agents is also considered, which is more in line with reality. Sufficient conditions for ensuring secure control of MASs and a parametric upper bound on the error vector norm between the agents and the leader are obtained. Finally, the numerical simulation verified the effectiveness of the proposed algorithm.
本文研究了混合网络攻击下多智能体系统（MASs）的领导者-跟随者同步问题，其中混合网络攻击是指通信信道中的欺骗攻击和多通道独立拒绝服务（DoS）攻击。为了实现混合网络攻击下MASs的安全控制，提出了一种基于拓扑切换的新型脉冲控制方法，并设计了一种确定脉冲时刻的新算法。此外，还考虑了智能体之间的合作-竞争关系，这更符合实际情况。得到了确保MASs安全控制的充分条件以及智能体与领导者之间误差向量范数的参数上界。最后，数值仿真验证了所提算法的有效性。
