具有时滞边界测量的反应扩散偏微分方程的边界输出反馈镇定

Boundary Output Feedback Stabilization of Reaction-Diffusion PDEs with Delayed Boundary Measurement

Hugo Lhachemi, Christophe Prieur

摘要:

研究了具有时滞边界测量的一般一维反应扩散偏微分方程的边界输出反馈镇定问题。输出采用Dirichlet或Neumann迹的形式。输出延迟可以任意大。该控制策略由一个有限维观测器和一个预测器组成,该观测器用于观测PDE的第一模式的延迟版本,该预测器用于获得在当前时间要应用的控制输入。对于任何给定的输出延迟值,我们评估所得到的闭环系统的稳定性,提供了观察器的顺序被选择足够大。利用这一结果,我们讨论的情况下,同时输入和输出延迟的控制策略的扩展。

英文摘要:

This paper addresses the boundary output feedback stabilization of general 1-D reaction-diffusion PDEs with delayed boundary measurement. The output takes the form of a either Dirichlet or Neumann trace. The output delay can be arbitrarily large. The control strategy is composed of a finite-dimensional observer that is used to observe a delayed version of the first modes of the PDE and a predictor component which is employed to obtain the control input to be applied at current time. For any given value of the output delay, we assess the stability of the resulting closed-loop system provided the order of the observer is selected large enough. Taking advantage of this result, we discuss the extension of the control strategy to the case of simultaneous input and output delays.
