H₂ control for networked control systems with Markovian datalosses and delays

This paper is concerned with the design of networked control systems withrandom network delay in the forward and feedback channel. A novel networkedpredictive controller combining H₂ control strategy is proposed toovercome the effects of network delay and data dropout. The necessary andsufficient conditions on the stability of the closed-loop networked controlsystem and an upper bound of H₂ are derived. It is shown that theclosed-loop networked predictive control system with bounded random networkdelay is stable if the corresponding Markovian system is stable. Also, nonlinearoptimization method is used to minimize the upper H₂ bound. ICIC International
