Full textWave and Schrödinger equations model a variety of phenomena, such as propagation of light, vibrating structures or the time evolution of a quantum particle. In these models, the high-energy asymptotics can be approximated by classical mechanics, as geometric optics. In this thesis, we study several applications of this principle to control problems for wave and Schrödinger equations in the Euclidean space, using microlocal analysis.In the first two chapters, we study the damped wave equation and the Schrödinger equation with a confining potential in the euclidean space. We provide necessary and sufficient conditions for uniform stability in the first case, or observability in the second one. These conditions involve the underlying classical dynamics which consists in a distorted version of geometric optics, due to the presence of the potential.Then in the third part, we analyze the quantum-classical correspondence principle in a general setting that encompasses the two aforementioned problems. We prove a version of Egorov's theorem in the Weyl--Hörmander framework of metrics on the phase space. We provide with various examples of application of this theorem for Schrödinger, half-wave and transport equations

Full textThe purpose of this thesis is to investigate the stabilization of certain second order evolution equations. First, we focus on studying the stabilization of locally weakly coupled second order evolution equations of hyperbolic type, characterized by direct damping in only one of the two equations. As such systems are not exponentially stable , we are interested in determining polynomial energy decay rates. Our main contributions concern abstract strong and polynomial stability properties, which are derived from the stability properties of two auxiliary problems: the sole damped equation and the equation with a damping related to the coupling operator. The main novelty is thatthe polynomial energy decay rates are obtained in several important situations previously unaddressed, including the case where the coupling operator is neither partially coercive nor necessarily bounded. The main tools used in our study are the frequency domain approach combined with new multipliers technique based on the solutions of the resolvent equations of the aforementioned auxiliary problems. The abstract framework developed is then illustrated by several concrete examples not treated before. Next, the stabilization of a two-dimensional Kirchhoff plate equation with generalized acoustic boundary conditions is examined. Employing a spectrum approach combined with a general criteria of Arendt-Batty, we first establish the strong stability of our model. We then prove that the system doesn't decay exponentially. However, provided that the coefficients of the acoustic boundary conditions satisfy certain assumptions we prove that the energy satisfies varying polynomial energy decay rates depending on the behavior of our auxiliary system. We also investigate the decay rate on domains satisfying multiplier boundary conditions. Further, we present some appropriate examples and show that our assumptions have been set correctly. Finally, we consider a wave wave transmission problem with generalized acoustic boundary conditions in one dimensional space, where we investigate the stability theoretically and numerically. In the theoretical part we prove that our system is strongly stable. We then present diverse polynomial energy decay rates provided that the coefficients of the acoustic boundary conditions satisfy some assumptions. we give relevant examples to show that our assumptions are correct. In the numerical part, we study a numerical approximation of our system using finite volume discretization in a spatial variable and finite difference scheme in time

Full textIn this thesis, we study the closely related theories of control, stabilization and propagation of singularities for some linear and nonlinear dispersive partial differential equations. Main results come from the author’s works:[1] Zhu, H., 2016. Stabilization of damped waves on spheres and Zoll surfaces of revolution. ESAIM: Control, Optimisation and Calculus of Variations (ESAIM: COCV), to appear.[2] Zhu, H., 2017. Control of three dimensional water waves. arXiv preprint arXiv:1712.06130.[3] Zhu, H., 2018. Propagation of singularities for gravity-capillary water waves. arXiv preprint arXiv:1810.09339.In [1] we studied the stabilization of the damped wave equation on Zoll surfaces of revolution. We gave an example where the region of damping is at the borderline of the geometric control condition, yet the damped waves exhibit a uniform exponential decay of energy, generalizing an example of Lebeau.In [2] we studied the controllability of the gravity-capillary water wave equation. Under the geometric control condition, we proved in arbitrary spatial dimension the exact controllability for spatially periodic small data. This generalizes a result of Alazard, Baldi and Han-Kwan for the 2D gravity-capillary water wave equation.In [3] we studied the propagation of singularities for the gravity-capillary water wave equation. We defined the quasi-homogeneous wavefront set, generalizing the wavefront set of H¨ ormander and the homogeneous wavefront set of Nakamura, and proved propagation results for quasi-homogeneous wavefront sets by the gravity-capillary water wave equation. As corollaries, we obtained local and microlocal smoothing effects for gravity-capillary water waves with sufficient spatial decay

Full textThis thesis is devoted to study the well-posedness and stabilization of some locally coupled systems. First, we study the well-posedness and stability of a one-dimensional Timoshenko system with localized internal fractional Kelvin-Voigt damping in a bounded domain. We investigate three cases : the first one, when the damping is localized in the bending moment, the second case when the damping is localized in the shear stress, we prove that the system is well posed in the sense of semigroup theory and its energy decays polynomially with rate t−1 in both cases. While, when the fractional Kelvin-Voigt is acting on the shear stress and the bending moment simultaneously, we show that the system is well posed in the sense of semigroup theory and polynomially stable, provided that the two dampings are acting in the same sub-interval. Second, we consider the generalized Rao-Nakra beam equation. The system consists of four waveequations for the longitudinal displacements and the shear angle of the top and bottom layers and one Euler-Bernoulli beam equation for the transversal displacement. We start by proving that the system is well posed in the sense of semigroup theory. Then, we study the stability problem. First, we show that the analytic stability holds when all the displacements are globally damped through Kelvin-Voigt damping. Second, we consider the case where the local damping acts only on the shear angle displacements of the top and bottom layers, and we obtain sufficient conditions for the system to be stronglystable. Using frequency domain arguments combined with the multiplier method, we prove that the energy of the system decays polynomially. Finally, we investigate the stability of a Bresse-type system in the whole line with a frictional damping working only on the first equation (vertical displacement). Our objectives are proving some stability and non-stability results depending on the parameters in the system. More precisely, we prove that, in some cases, the system is polynomially stable, and in some other cases, the solution does not converge to zero at all. The proofs are based on the energy method and Fourier analysis combined with some well choosen weight functions
Klein, Guillaume. "Stabilisation et asymptotique spectrale de l’équation des ondes amorties vectorielle." Thesis, Strasbourg, 2018. http://www.theses.fr/2018STRAD050/document.
Full textIn this thesis we are considering the vectorial damped wave equation on a compact and smooth Riemannian manifold without boundary. The damping term is a smooth function from the manifold to the space of Hermitian matrices of size n. The solutions of this équation are thus vectorial. We start by computing the best exponential energy decay rate of the solutions in terms of the damping term. This allows us to deduce a sufficient and necessary condition for strong stabilization of the vectorial damped wave equation. We also show the appearance of a new phenomenon of high-frequency overdamping that did not exists in the scalar case. In the second half of the thesis we look at the asymptotic distribution of eigenfrequencies of the vectorial damped wave equation. Were show that, up to a null density subset, all the eigenfrequencies are in a strip parallel to the imaginary axis. The width of this strip is determined by the Lyapunov exponents of a dynamical system defined from the damping term

In this thesis, the problems of pointwise control design and exponential stabilization for the semilinear parabolic distributed parameter systems are investigated. Firstly, a distributed parameter system which is expressed by the nonlinear parabolic partial differential equation (PDE) system is modeled as a polynomial fuzzy parabolic PDE system by Taylor’s series identification approach. For controller design, three kinds of fuzzy controllers are designed for the polynomial fuzzy parabolic PDE system including full state feedback, pointwise state feedback, and collocated pointwise state feedback. By examining the stability analysis, based on the homogeneous polynomial Lyapunov function, Euler's homogeneous relation, and vector-valued Wirtinger's inequality, three different exponential stabilization conditions are proposed in terms of sum-of-squares (SOS). Lastly, a physical system and a numerical example are illustrated to show the feasibility and validity of the proposed methods.
