关于heat equation边界控制的可达状态

On the reachable states for the boundary control of the heat equation

Philippe Martin, Lionel Rosier, Pierre Rouchon

摘要:

我们感兴趣的是一维热方程边界控制的可达态的确定。我们考虑一个或两个边界控制。我们证明了与平方可积〔的〕控制相关的可达状态可以推广到C的某个平方上的解析函数,反之,定义在某个圆盘上的解析函数可以通过使用二阶Gevrey函数的边界控制来达到.证明方法是将平坦性方法与Gevrey类中的新Borel内插定理相结合,并给出了插值函数的逐次导数的一致估计的损失值.

英文摘要:

We are interested in the determination of the reachable states for the boundary control of the one-dimensional heat equation. We consider either one or two boundary controls. We show that reachable states associated with square integrable controls can be extended to analytic functions onsome square of C, and conversely, that analytic functions defined on a certain disk can be reached by using boundary controlsthat are Gevrey functions of order 2. The method of proof combines the flatness approach with some new Borel interpolation theorem in some Gevrey class witha specified value of the loss in the uniform estimates of the successive derivatives of the interpolating function.
