具有异常Agent和控制层的互连多Agent系统的事件触发分布式镇定:理论分析
Event-Triggered Distributed Stabilization of Interconnected Multiagent Systems with Abnormal Agent and Control Layers: Theoretical Analysis
摘要:
最近已经提出了一个图论框架,以稳定互连的多智能体系统在分布式的方式,同时系统地捕获的体系结构方面的网络物理系统与单独的代理或物理层和控制或网络层。基于这一发展,除了代理层的建模不确定性,我们考虑的情况下,控制层受到拒绝服务攻击。我们提出了一个循序渐进的过程来设计一个控制层,在存在上述异常的情况下,保证了最终的两层互联多智能体系统的鲁棒性和弹性水平。事件触发策略的结合进一步确保了控制层上有限的能量和通信资源的有效使用。我们从理论上证明了弹性,鲁棒性,和Zeno的所有状态轨迹收敛到原点,并通过仿真研究,讨论了所提出的想法的可行性。
英文摘要:
A graph theoretic framework recently has been proposed to stabilize interconnected multiagent systems in a distributed fashion, while systematically capturing the architectural aspect of cyber-physical systems with separate agent or physical layer and control or cyber layer. Based on that development, in addition to the modeling uncertainties over the agent layer, we consider a scenario where the control layer is subject to the denial of service attacks. We propose a step-by-step procedure to design a control layer that, in the presence of the aforementioned abnormalities, guarantees a level of robustness and resiliency for the final two-layer interconnected multiagent system. The incorporation of an event-triggered strategy further ensures an effective use of the limited energy and communication resources over the control layer. We theoretically prove the resilient, robust, and Zeno-free convergence of all state trajectories to the origin and, via a simulation study, discuss the feasibility of the proposed ideas.
