论文摘要
网络物理系统的威胁已经变成了避开传统安全和保护方法的一定程度。这项工作介绍了一种积极主动的方法来实现飞行无人机的网络安全性。在存在非合件（有缺陷或恶意）无人机的存在下，对无人机的弹性形成控制。基于本地信息，在出现不耐受性的共识算法的情况下，在出现不良节点的存在下的弹性共识。在提出的框架中，引入了网络鲁棒性的图理论属性，该网络鲁棒性传达了网络中两组无人机之间直接信息交换的概念，以分析分布式共识算法的行为和收敛性。制定了分布式控制策略以维持网络连接阈值，以满足共识算法的弹性提出的拓扑要求。列出了数值示例，以说明用于处理网络攻击享受的主动方法的适用性
The threats on cyber-physical system have changed much into a level of sophistication that elude the traditional security and protection methods. This work addresses a proactive approaches to the cyber security of a formation flying UAVs. A resilient formation control of UAVs in the presence of non-cooperative (defective or malicious) UAVs is presented. Based on local information a resilient consensus in the presence of misbehaving nodes is dealt with fault-tolerant consensus algorithm. In the proposed framework, a graph-theoretic property of network robustness conveying the notion of a direct information exchange between two sets of UAVs in the network is introduced to analyze the behavior and convergence of the distributed consensus algorithm. A distributed control policy is developed to maintain the network connectivity threshold to satisfy the topological requirement put forward for the resiliency of the consensus algorithm. Numerical examples are presented to show the applicability of the proactive approach used in dealing with the cyber attack treat on a formation flying UAVs
