| 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.

| Abstract: | Because the communication networks are produced in the network control system, The uncertainty of the net- work induced delay, the loss of the data pack and the data wrap cycle time conf used etc arouse, which influence the stable function of t he system to even cause system seriously of unsteady. Delayed for more than a clock, this paper makes dif- ferential equations to describe the system with the delay. The stability conditions with the delay are derived by Lyapunov- krasovskii theorem. Finally simulati... |
