在对网络控制系统稳定性技术研究的基础上,本文提出将NCS中的数据包丢失视作一个随机事件,同时把NCS中丢包问题视作一个切换系统来对丢包控制系统建模,利用MLF(Multiple Lyapunov Functions)来分析NCS的丢包率与系统渐近稳定性的关系,最后通过理论分析得出了系统渐近稳定时数据包丢失率的上边界值。 Based on the research on the stability of networked control system, this paper proposes to consider the packet loss in NCS as a random event, at the same time, consider the problem of packet loss in NCS as a switching system to model and control the packet loss control system MLF (Multiple Lyapunov Functions) to analyze the relationship between the NCS packet loss rate and the asymptotic stability of the system. Finally, by theoretical analysis, the upper bound of packet loss rate is obtained when the system is asymptotically stable.
