Considering the uncertain delay of networked control systems(NCS),with the sensor node of NCS time-driven.and acuatorand controllers event.driven,the networke control systems was modeled as an uncertain discrete liner system.Then it constructed one lyaupon function,using the relevant knowledge of liner matrix inequalities (LMIs),analyzing the stability of the system,and giving one suficient condition for system stability.At last,an example was given.The simulation results verify the effectiveness of the method.
