AI总结:

针对带时变和空变系数的一维线性双曲平衡律的有限时间边界镇定问题,拓展反步法引入含时积分变换,处理了非标准多维双曲PDE核的适定性难点,推广了仅适用于时不变系统的已有结果。

摘要:

本文研究具有时变和空变系数的一维线性双曲平衡律的有限时间边界镇定问题。我们对所谓的“backstepping方法(反步法)”进行了拓展,引入合适的含时积分变换,将初始系统映射为一个具备理想稳定特性的新系统。所涉及积分变换的核是一类非标准多维双曲偏微分方程(PDEs)的解,其中时间依赖性给其适定性的处理带来了若干新的难点。本工作推广了文献中仅考虑时不变系统的已有结果。

英文摘要:

In this article we are interested in the boundary stabilization in finite time of one-dimensional linear hyperbolic balance laws with coefficients depending on time and space. We extend the so called "backstepping method" by introducing appropriate time-dependent integral transformations in order to map our initial system to a new one which has desired stability properties. The kernels of the integral transformations involved are solutions to non standard multi-dimensional hyperbolic PDEs, where the time dependence introduces several new difficulties in the treatment of their well-posedness. This work generalizes previous results of the literature, where only time-independent systems were considered.
