Inter-regional modeling and control strategy research of networked control system

This paper considers the modeling and stabilization problem of NCS (networked control system) which contains a wide-area control object. Signals from sensors installed in the field are classified into two style: local signals and remote signal. Considering packet loss problem of the remote signals. NCS is modeled as an inter-regional switching system. Sufficient conditions on stability and stabilization of such NCSs are presented. Using LMI toolbox, a numerical example is worked out to demonstrate the feasibility and efficiency of the proposed method.
