STUDY OF EXPONENTIAL STABILITY OF COUPLED WAVE SYSTEMS VIA DISTRIBUTED STABILIZER

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 28, Issue 8, Page 479-491, 2001., 2001
Stabilization of the system of wave equations coupled in parallel with coupling distributed springs and viscous dampers are under investigation due to different bound- ary conditions and wave propagation speeds.

Efficient criteria for the stabilization of planar linear systems by hybrid feedback controls

open access: yesAbstract and Applied Analysis, Volume 2004, Issue 6, Page 487-499, 2004., 2004
We suggest some criteria for the stabilization of planar linear systems via linear hybrid feedback controls. The results are formulated in terms of the input matrices. For instance, this enables us to work out an algorithm which is directly suitable for a computer realization. At the same time, this algorithm helps to check easily if a given linear 2 ×

Dynamic boundary controls of a rotating body‐beam system with time‐varying angular velocity

open access: yesJournal of Applied Mathematics, Volume 2004, Issue 2, Page 107-126, 2004., 2004
This paper deals with feedback stabilization of a flexible beam clamped at a rigid body and free at the other end. We assume that there is no damping and the rigid body rotates with a nonconstant angular velocity. To stabilize this system, we propose a feedback law which consists of a control torque applied on the rigid body and either a dynamic ...

Exponentially dissipative nonlinear dynamical systems: a nonlinear extension of strict positive realness

open access: yesMathematical Problems in Engineering, Volume 2003, Issue 1, Page 25-45, 2003., 2003
We extend the notion of dissipative dynamical systems to formalize the concept of the nonlinear analog of strict positive realness and strict bounded realness. In particular, using exponentially weighted system storage functions with appropriate exponentially weighted supply rates, we introduce the concept of exponential dissipativity.

Nonsmooth optimal regulation and discontinuous stabilization

open access: yesAbstract and Applied Analysis, Volume 2003, Issue 20, Page 1159-1195, 2003., 2003
For affine control systems, we study the relationship between an optimal regulation problem on the infinite horizon and stabilizability. We are interested in the case the value function of the optimal regulation problem is not smooth and feedback laws involved in stabilizability may be discontinuous.

Control and Stabilization of High-Order KdV Equation Posed on the Periodic Domain

open access: yesJournal of Partial Differential Equations, 2018
In this paper, we study exact controllability and feedback stabilization for the distributed parameter control system described by high-order KdV equation posed on a periodic domain T with an internal control acting on an arbitrary small nonempty ...

General decay in a Timoshenko-type system with thermoelasticity with second sound

open access: yesAdvances in Nonlinear Analysis, 2015
In this article, we consider a vibrating nonlinear Timoshenko system with thermoelasticity with second sound. We discuss the well-posedness and the regularity of solutions using the semi-group theory.

Almost Global Stochastic Stability [PDF]

open access: yes, 2005
We develop a method to prove almost global stability of stochastic differential equations in the sense that almost every initial point (with respect to the Lebesgue measure) is asymptotically attracted to the origin with unit probability.

Coexistence for a kind of stochastic three-species competitive models

open access: yesOpen Mathematics, 2019
The coexistence of species sustains the ecological balance in nature. This paper focuses on sufficient conditions for the coexistence of a three-species stochastic competitive model, where the model has non-linear diffusion parts.

Inertial manifolds and stabilization of nonlinear beam equations with Balakrishnan‐Taylor damping

open access: yesAbstract and Applied Analysis, Volume 1, Issue 1, Page 83-102, 1996., 1996
In this paper we study a hinged, extensible, and elastic nonlinear beam equation with structural damping and Balakrishnan‐Taylor damping with the full exponent 2(n + β) + 1. This strongly nonlinear equation, initially proposed by Balakrishnan and Taylor in 1989, is a very general and useful model for large aerospace structures.
