论文摘要
本文考虑了在传感器攻击存在下的离散时间线性时间流（LTI）系统的分布式状态观察者的设计。我们假设有一个观察者节点网络，可以通过一个无方向的图形进行通信，每个图都对某些对抗性攻击损坏的输出进行了部分测量。我们解决了稀疏攻击的情况，攻击者瞄准了一小部分传感器。开发了基于乘数的交替方向方法（ADMM）的算法，该算法为每个观察者提供了更新定律，以确保每个观察者节点的收敛到实际状态渐近状态。
This paper considers the design of a distributed state-observer for discrete-time Linear Time-Invariant (LTI) systems in the presence of sensor attacks. We assume there is a network of observer nodes, communicating with each other over an undirected graph, each with partial measurements of the output corrupted by some adversarial attack. We address the case of sparse attacks where the attacker targets a small subset of sensors. An algorithm based on Alternating Direction Method of Multipliers (ADMM) is developed which provides an update law for each observer which ensures convergence of each observer node to the actual state asymptotically.
