The problem of filter design is considered for continuous-time linear stochastic systems using distributed sensors. Each sensor unit, represented by a node in an undirected and connected graph, collects some information about the state communicates its own estimate with neighbors. It stipulated that this communication between nodes edge time-sampled randomly each edge, sampling process independ...

This paper presents a novel conditionally suboptimal filtering algorithm on estimation problems that arise in discrete nonlinear time-varying stochastic difference systems. The suboptimal state estimate is formed by summing of conditionally nonlinear filtering estimates that their weights depend only on time instants, in contrast to conditionally optimal filtering, the proposed conditionally su...

In this paper we show how to compute suboptimal H 1 controllers, for a class of (possibly) unstable and (possibly) innnite dimensional plants, from a nite set of linear equations. A solution to the H 1 suboptimal control problem for innnite dimensional stable plants was obtained in 6]. Also, in 13] and 14] the H 1 optimal control problem was solved for unstable distributed plants. Our solution ...
