摘要
针对闭环网络控制系统,在考虑网络数据传输可能发生丢包的情况下,提出了一类切换系统模型,并在此基础上导出了一类脉冲微分系统模型.从数学上严格分析了该模型的合理性,并利用驻留时间的概念得到了此系统模型的稳定性条件,进一步研究了能够忍受一定程度的数据丢包的稳定化控制器设计问题.最后给出了一个具体示例.
In this paper, a switched system model is presented for networked control systems with data packet dropouts, Moreover an impulsive system model is obtained from this switched system. The exponential stability of the impulsive system is studied by introducing the concept of dwell-time. A state feedback controller with tolerance of certain data dropouts is designed. Main results are given in linear matrix inequalities. Finally a numerical example is shown to demonstrate the theoretical results.
