摘要

本文利用多面体李雅普诺夫函数,研究了具有恒定、未知或时变有界传输延迟的网络控制系统(NCS)的稳定性分析和控制设计。首先,给出了具有结构不确定性的等效增广离散系统的稳定性保证条件。然后,建立了具有有界时变时滞的网络控制系统的线性状态反馈控制器计算的代数条件。稳定性分析和综合问题都简化为线性规划方法,这是由于选择多面体李雅普诺夫函数而产生的一个可喜的结果。

A polyhedral approach to the stability analysis and feedback stabilization of networked control systems
In this note, the stability analysis and control design of Networked Control Systems (NCS) with bounded transmission delays, constant and unknown or time varying, is investigated using polyhedral Lyapunov functions. First, conditions guaranteeing stability are formulated for the equivalent augmented discrete-time system with structured uncertainties. Then, algebraic conditions leading to the computation of a linear state feedback controller for a NCS with bounded time varying delays are established. Both the stability analysis and synthesis problem are reduced to linear programming methods, a welcome consequence stemming from the choice of polyhedral Lyapunov functions.
