A uniformly controllable and implicit scheme for the 1-D wave equation
ESAIM: Modélisation mathématique et analyse numérique, Tome 39 (2005) no. 2, pp. 377-418.

This paper studies the exact controllability of a finite dimensional system obtained by discretizing in space and time the linear 1-D wave system with a boundary control at one extreme. It is known that usual schemes obtained with finite difference or finite element methods are not uniformly controllable with respect to the discretization parameters h and Δt. We introduce an implicit finite difference scheme which differs from the usual centered one by additional terms of order h 2 and Δt 2 . Using a discrete version of Ingham’s inequality for nonharmonic Fourier series and spectral properties of the scheme, we show that the associated control can be chosen uniformly bounded in L 2 (0,T) and in such a way that it converges to the HUM control of the continuous wave, i.e. the minimal L 2 -norm control. The results are illustrated with several numerical experiments.
