网络攻击下不确定多智能体动态事件触发一致性

Consistency of Uncertain Multi-agent Under Network Attacks with Dynamic-Event-Triggering Mechanism

研究了网络攻击下具有不确定性多智能体系统动态事件触发一致性问题。传统的事件触发机制无法通过改变触发规则来有效地节约网络资源。通过引入动态事件触发机制,利用该机制的动态变量使设计的事件触发条件可以根据系统的运行状态进行动态调整,从而降低控制更新的频率。在时延控制输入、网络攻击及动态事件触发下,建立了闭环控制系统的数学模型。根据Lyapunov稳定性理论和线性矩阵不等式理论,证明了动态事件触发控制下多智能体系统的一致性。最后,通过仿真验证了该方法的可行性和有效性。

The consistency of uncertain multi-agent systems based on dynamic event triggering mechanism under network attacks is studied.Traditional event triggering mechanisms cannot effectively save network resources by changing the triggering rules.Dynamic event-triggering mechanism is introduced.On the basis of the dynamic variables of the mechanism,the event triggering conditions are dynamically adjusted according to the running state of the system,so as to reduce the frequency of control updates.The mathematical model of the closed-loop control system is established under the delay control input,network attacks and the trigger of dynamic events.The consistency of multi-agent systems under dynamic event triggering control is proved by Lyapunov stability theory and Linear Matrix Inequality(LMI) theory.Finally,the effectiveness of the proposed method is verified by simulation experiments.
