摘要
网络控制系统中由于通讯网络的引入产生了不确定的网络延时、数据包丢失以及数据包时序错乱等问题,这些问题严重影响了系统的稳定性能甚至引起了系统的不稳定.针对延迟大于一个时钟的情况,本文通过微分方程来描述有延迟的系统.通过Lyapunov-krasovskii定理推导出带有延迟的系统的稳定条件.最后结果验证了稳定性结论.
Because the communication networks are produced in the network control system, The uncertainty of the network induced delay, the loss of the data pack and the data wrap cycle time confused etc arouse, which influence the stable function oft he system to even cause system seriously of unsteady. Delayed for more than a clock, this paper makes differential equations to describe the system with the delay. The stability conditions with the delay are derived by Lyapunovkrasovskii theorem. Finally simulation results show the stability of conclusions.
