EXPONENTIAL STABILITY OF AXIALLY MOVING KIRCHHOFF-BEAM SYSTEMS WITH NONLINEAR BOUNDARY DAMPING AND DISTURBANCE

This paper examines the stabilization problem of the axially moving Kirchhoff beam. Under the nonlinear damping criterion established by the slope-restricted condition, the existence and uniqueness of solutions of the closed-loop system equipped with nonlinear time-delay disturbance at the boundary is investigated via the Faedo-Galerkin approximation method. Furthermore, the solution is continuously dependent on initial conditions. Then the exponential stability of the closed-loop system is established by the direct Lyapunov method, where a novel energy function is constructed.
