【Abstract】 The stability of the model-based network control system with delays is studied.Using knowledge of the plant dynamics,the model-based network control system reduces the number of packet exchanges and fits the network traffic.Necessary and sufficient conditions for stability are derived for the presented setup in terms of the update time h and network delay time τ.The simulation results by Matlab demonstrate that the proposed methods are feasible and effective.更多还原
