AI总结:

本文研究了耦合抛物型偏微分方程组的零可控性问题,重点探讨了通过一阶和零阶耦合以及欠驱动特性子类的控制问题,采用分析和代数方法分别证明了通过内部控制实现零可控性。

摘要:

本文研究了耦合抛物型偏微分方程组的零可控性问题。特别是,我们的工作专注于一类重要的控制问题子类,这些问题通过一阶和零阶耦合连接,并且此外是欠驱动的。我们将控制问题置于一个相对较新的框架中,将问题分解为相互关联的部分:我们将第一部分称为分析控制问题,其中我们使用稍微非经典的技巧通过出现在每个方程中的内部控制来证明零可控性;我们将第二部分称为代数控制问题,其中我们使用代数方法来逆解一个描述我们系统的线性偏微分算子,这使得我们能够通过只出现在少数方程中的内部控制来恢复零可控性。通过同时解决这些控制问题,我们建立了原始问题的零可控性结果。

英文摘要:

This work studies the null controllability of a system of coupled parabolic PDEs. In particular, our work specializes to an important subclass of these control problems which are coupled by first and zero-order couplings and are, additionally, underactuated. We pose our control problem in a fairly new framework which divides the problem into interconnected parts: we refer to the first part as the analytic control problem, where we use slightly non-classical techniques to prove null controllability by means of internal controls appearing on every equation; we refer to the second part as the algebraic control problem, where we use an algebraic method to invert a linear partial differential operator that describes our system; this allows us to recover null controllability by means of internal controls which appear on only a few of the equations. We establish a null controllability result for the original problem by solving these control problems concurrently.
