摘要

This article investigates the H-2 and H-8. suboptimal distributed filtering problems for continuous-time linear systems. We consider a linear system monitored by a number of filters, where each of the filters receive only part of the measured output of the system. Each filter can communicate with the other filters according to a priori given strongly connected weighted directed graph. The aim is to design filter gains that guarantee the H-2 or H-8. norm of the transfer matrix from the disturbance input to the output estimation error to be smaller than a priori given upper bound, while all local filters reconstruct the full system state asymptotically. We provide a centralized design method for obtain-ing such H-2 and H-8. suboptimal distributed filters. The proposed design method is illustrated by a simulation example.
