中文摘要:针对一类具有状态时变时滞且模型中具有参数摄动的网络控制系统,通过构造输入时滞、添加自由矩阵的技巧,利用Lyapunov 泛函和线性矩阵不等式工具,得到闭环系统鲁棒渐近稳定且满足给定H∞扰动抑制水平γ的时滞条件,并给出系统的鲁棒H∞状态反馈控制器的设计方法。所用方法适合时滞以任何速度变化的系统,且不需要知道时滞的导数信息。最后用实例仿真证明了结论的有效性。

Robust H∞ State-feedback Controller Design for a Class of Networked Control Systems
Abstract:This paper focuses on a class of networked control system with time varying delays and state time varying delays and the uncertainty parameters. Take advateage of the free weighting matrix and input time delay, the closed-loop system has been robust asymptotically stable and satisfied the given H∞ disturbances rejection level of the delay-dependent conditions by using Lyapunov functional and linear matrix inequality. At the same time, the robust H∞ State-feedback controller design method is also given. This method has no limit on the time delay derivation and suits any speed varying system. Finally, an application simulation results prove the effectiveness of the conclusion.
