反应扩散偏微分方程的事件触发增益调度

Event-triggered gain scheduling of reaction-diffusion PDEs

Iasson Karafyllis, Nicolas Espitia, Miroslav Krstic

摘要:

本文研究了反应系数随时间和空间变化的一维反应扩散偏微分方程的边界稳定性问题。边界控制设计依赖于反推方法。边界控制的增益在两个合适的事件触发机制下被调度。更准确地说,根据两个状态依赖的事件相关事件触发条件(基于静态和基于动态的条件)来计算/更新事件上的增益,在这两个条件下,避免了芝诺行为并且保证了闭环系统的适定性以及指数稳定性。数值模拟来说明结果。

英文摘要:

This paper deals with the problem of boundary stabilization of 1D reaction-diffusion PDEs with a time- and space- varying reaction coefficient. The boundary control design relies on the backstepping approach. The gains of the boundary control are scheduled under two suitable event-triggered mechanisms. More precisely, gains are computed/updated on events according to two state-dependent event-triggering conditions: static-based and dynamic-based conditions, under which, the Zeno behavior is avoided and well-posedness as well as exponential stability of the closed-loop system are guaranteed. Numerical simulations are presented to illustrate the results.
