论文摘要
在本文中，我们介绍了传感器攻击下线性动力学系统的完全分布的弹性状态估计方案。所提出的状态观察者由一个本地观察者网络组成，其中每个观察者都利用局部测量和从邻居传递的信息。作为一个完全分布的方案，它不一定是为了攻击识别而收集大多数传感数据，而折衷的传感器最终被分布式网络识别并被排除在观察者之外。为此，假定总体网络（不是单个本地观察者）具有冗余传感器并被假定连接。所提出的方案是基于分布式求解器的新型设计，该设计大致恢复了局部估计值的中值。
In this paper, we present a scheme of fully distributed resilient state estimation for linear dynamical systems under sensor attacks. The proposed state observer consists of a network of local observers, where each of them utilizes local measurements and information transmitted from the neighbors. As a fully distributed scheme, it does not necessarily collect a majority of sensing data for the sake of attack identification, while the compromised sensors are eventually identified by the distributed network and excluded from the observers. For this, the overall network (not the individual local observer) is assumed to have redundant sensors and assumed to be connected. The proposed scheme is based on a novel design of a distributed median solver, which approximately recovers the median value of local estimates.
