Well-posedness for systems representing electromagnetic/acoustic wavefront interaction

H. T. Banks, J. K. Raye (2002)

ESAIM: Control, Optimisation and Calculus of Variations

Similarity:

In this paper we consider dispersive electromagnetic systems in dielectric materials in the presence of acoustic wavefronts. A theory for existence, uniqueness, and continuous dependence on data is presented for a general class of systems which include acoustic pressure-dependent Debye polarization models for dielectric materials.

Exact controllability of the wave equation with mixed boundary condition and time-dependent coefficients

M. M. Cavalcanti (1999)

Archivum Mathematicum

Similarity:

In this paper we study the boundary exact controllability for the equation t α ( t ) y t - j = 1 n x j β ( t ) a ( x ) y x j = 0 in Ω × ( 0 , T ) , when the control action is of Dirichlet-Neumann form and Ω is a bounded domain in R n . The result is obtained by applying the HUM (Hilbert Uniqueness Method) due to J. L. Lions.

Exact boundary controllability of a hybrid system of elasticity by the HUM method

Bopeng Rao (2001)

ESAIM: Control, Optimisation and Calculus of Variations

Similarity:

We consider the exact controllability of a hybrid system consisting of an elastic beam, clamped at one end and attached at the other end to a rigid antenna. Such a system is governed by one partial differential equation and two ordinary differential equations. Using the HUM method, we prove that the hybrid system is exactly controllable in an arbitrarily short time in the usual energy space.
