Optimal Control Design for the Stabilization of Network Controlled Systems

In this paper, the problem of remote output stabilization of networked control systems is investigated. The network is considered as a time-varying delay in the communication channel. An average model of the delay dynamics is supposed to be known and the unpredicted events occurring on the network are introduced as a random input in these dynamics. The authors propose a constructive control scheme where the deterministic aspect of the network is explicitly taken into account in a predictor-based feedback law. A stochastic descent algorithm is then introduced to set the controller gain according to the non-deterministic part of the delay dynamics. Some simulation results are also presented.
