论文摘要
本文研究了连续时间线性系统的H2和H-触发次优的分布式过滤问题。考虑一个由许多过滤器监视的线性系统，其中每个过滤器仅接收系统测量输出的一部分。每个过滤器都可以根据先验鉴定的加权定向图与其他过滤器进行通信。目的是设计从干扰输入到输出估计误差的传输矩阵的H2或H-凸数标准的滤波器获得，而不是先验给定的上限，而所有本地过滤器都会渐近地重建完整的系统状态。我们提供了一种集中的设计方法，用于获得此类H2和H-触发次优的分布式过滤器。提出的设计方法通过仿真示例说明。
This paper investigates the H2 and H-infinity suboptimal distributed filtering problems for continuous time linear systems. Consider a linear system monitored by a number of filters, where each of the filters receives only part of the measured output of the system. Each filter can communicate with the other filters according to an a priori given strongly connected weighted directed graph. The aim is to design filter gains that guarantee the H2 or H-infinity norm of the transfer matrix from the disturbance input to the output estimation error to be smaller than an a priori given upper bound, while all local filters reconstruct the full system state asymptotically. We provide a centralized design method for obtaining such H2 and H-infinity suboptimal distributed filters. The proposed design method is illustrated by a simulation example.
