Stable controller Design for large-scale systems with missing measurements and system delay

摘要

A state feedback controller design for a class of linear discrete-time large-scale system with missing measurements and one step system delay is considered in this paper.The linear discrete-time large-scale system was modeled as interconnection of N subsystems.The occurrence of missing measurement is assumed to be a Bernoulli distributed sequence with known probability.Every subsystem has one step system delay.Sufficient conditions for the existence of a controller are derived in terms of linear matrix inequality(LMI),such that the closed-loop system exponentially stable in the sense of mean square.A numerical example is also provided to demonstrate the validity of the proposed design approach.
