| Abstract: | The asymptotical stabilization problem of networked control systems is studied under communication constraints which cause system information loss. The stability and performance of the closed loop system are then not only determined by the characteristics of the control system, but also determined by the scheduling manner imposed by network. A simple information scheduling scheme is presented and the admissibility problem of such information scheduling approach is also studied through the stability justification of the closed loop system for given sampling manner. A numerical example illustrates the proposed method. |
