摘　　要：为了解决抛物型多智能体系统(MASs)在拒绝服务(DoS)攻击下的一致性问题,提出了一种基于输出反馈方法的MASs领导-跟随一致性控制协议来应对恶意攻击者发起的DoS攻击,从而实现智能体在无向通信拓扑图上的领导-跟随一致性。对DoS攻击的频率和持续时间进行了分析,利用Lyapunov稳定性定理推导了抛物型偏微分系统的稳定条件,证明了触发时间间隔不为零,避免了芝诺行为的发生,并通过仿真算例验证了理论结果的有效性。In order to solve the consensus problem of parabolic multi-agent systems(MASs)under denial of service(DoS)attacks,the leader-follower consensus control protocol based on output feedback method was proposed for MASs to deal with DoS attacks initiated by malicious attackers,in order to achieve leader-follower consistency on undirected communication topology of agents.In addition,the frequency and duration of DoS attacks were analyzed,and the necessary and sufficient conditions for the stability of parabolic partial differential systems were derived by Lyapunov stability theorem.It is confirmed that the time interval between events is not zero,eliminating the occurrence of Zeno behavior,and the effectiveness of theoretical results is verified through simulation examples.
