| 摘 要： | 由于系统建模的误差和工作环境的变化,系统的不确定性不可避免.针对具有时变结构参数不确定性的网络控制系统,本文通过设置逻辑零阶保持器来处理错序和丢包问题,并且引入自由权矩阵消除交叉项等处理方式,推导出使闭环网络控制系统渐进稳定的充分条件.仿真结果验证了此分析结果的有效性和可行性.

| Abstract: | Due to the error of system modelling and the change of working environment,the uncertainty of the system is inevitable.This paper presents an improved analysis method for networked control systems with time-varying structural parameter uncertainry.By setting the logic Zero-order holder(ZOH)which makes the packet out-of-order and data dropout is dealed with.We employ the free weighting matrices to deal with cross product items in our derivation to obtain the sufficient condition of the closed-loop system asymptotically stable.Finally,the simulation example shows the effectiveness and feasibility of the presented method. |
