Controllability Problems for the Heat Equation with Variable Coefficients on a Half-Axis Controlled by the Neumann Boundary Condition

Larissa Fardigola, Kateryna Khalina

摘要:

本文研究了控制系统$w_t=\frac{1}ρ\left(kw_x\right)_x+γw$,$\left.\left(\sqrt{\frac{k}ρ}w_x\right)\right|_{x=0}=u$,$x>0$,$t\in(0,T)$的能控性和近似能控性问题,其中$u$是控制,$u\in L^\infty(0,T)$ .证明了控制系统的每个初始状态在给定时间$T>0$内可近似控制到任意目标状态。为了获得该结果,应用由方程数据$ρ$、$k$、$γ$生成的变换算子。最后用实例说明了结果。

英文摘要:

In the paper, the problems of controllability and approximate controllability are studied for the control system $w_t=\frac{1}ρ\left(kw_x\right)_x+γw$, $\left.\left(\sqrt{\frac{k}ρ}w_x\right)\right|_{x=0}=u$, $x>0$, $t\in(0,T)$, where $u$ is a control, $u\in L^\infty(0,T)$. It is proved that each initial state of the control system is approximately controllable to any target state in a given time $T>0$. To obtain this result, the transformation operator generated by the equation data $ρ$, $k$, $γ$ is applied. The results are illustrated by examples.
