摘要
网络控制系统指的是由网络组成的一个闭环的反馈控制系统。数据包丢失会造成网络控制系统的性能降低,对其稳定性产生不利影响。本文在忽略网络诱导时延的影响下,构建了单数据包丢失的网络控制系统模型,然后给出了稳定性分析的定理,最后通过对实际系统的计算和仿真进一步确定了丢包对系统稳定性的影响。
Network control system refers to a closed-loop feedback control system composed of networks.Packet loss will reduce the performance of network control system and adversely affect its stability.In this paper,the network control system model of single packet loss is constructed without considering the influence of network-induced delay,and then the stability analysis theorem is given.Finally,the influence of packet loss on system stability is further determined through the calculation and simulation of the actual system.
