Abstract

This paper scrutinizes the consensus problem of nonlinear multi-agent cyber-physical systems through hybrid-triggered control. Initially, the nonlinearities of multi-agent cyber-physical systems are employed with incremental quadratic constraints, which are represented by incremental quadratic matrices. It is to be noted that hybrid-triggered technique switches between time-triggered and event-triggered protocols in order to efficiently reduce the network bandwidth load. Further, with the aim of providing a resilient and secure communication, the control is formulated with gain fluctuations and the effects of cyber attacks such as denial-of-service attacks. By exploiting an appropriate Lyapunov-Krasovskii functional (LKF) and utilizing Peng-Park integral inequality, adequate conditions are acquired in terms of linear matrix inequalities (LMIs). Eventually, the efficacy of theoretical findings are illustrated with numerical simulations.

基于混合触发的增量二次约束和拒绝服务攻击非线性多智能体网络物理系统一致性非脆弱控制

研究了基于混合触发控制的非线性多智能体网络物理系统的一致性问题。首先，将多智能体网络物理系统的非线性问题引入增量二次约束，用增量二次矩阵表示。值得注意的是，混合触发技术在时间触发和事件触发协议之间进行切换，以有效地减少网络带宽负载。此外，为了提供有弹性和安全的通信，在制定控制时考虑了增益波动和网络攻击（如拒绝服务攻击）的影响。利用适当的Lyapunov-Krasovskii泛函（LKF）和Peng-Park积分不等式，得到了线性矩阵不等式的充分条件。最后，通过数值模拟验证了理论结果的有效性。
