Combination of local and remote controllers design for a networked control system

In this paper, an H_∞ state feedback control problem for a generalized state-space system is considered. For the system, we propose a controller module consists of a local controller and a remote one under networked framework. The remote controller could improve the control efficiency of the local controller to the plant when the correlated networked feedback system is working with measurement data lose or transmission delay. We utilize a modified finite sum inequality approach to derive a set of delay-dependent LMI-based sufficient conditions for the admissibility (generalized stability) analysis and controllers synthesis problems, respectively. At the end of this paper, we also present a numerical example to show the feasibility of the proposed conditions.
