网络H_∞控制系统的建模与分析

Model-Building and Analysis of Network H_∞ Control System

给出了引入干扰后静态状态反馈网络H∞控制系统的模型及网络延迟小于采样周期情况下网络控制系统的γ-次优H∞静态状态反馈控制器的设计方法。仿真结果表明,用该方法设计的控制器构成的闭环系统是稳定的,并且在偶然丢包的情况下,使用该控制器控制闭环系统也是稳定的。

By introducing the network interference, the H∞ control system model of a static-state feedback network, and the design of the suboptimal H∞ static-state feedback controller are proposed when the network delay is less than the sampling period. The simulation results demonstrate that the closed-loop system constructed by this method is stable and stable too in the condition of occasional packet loss.
