Abstract: The stabilization problem of Euler-Bernoulli beam via nonlinear boundary dissipative feedback is considered. Firstly, by virtue of nonlinear semigroup theory and energy-perturbed method, it is shown that the vibration of the beam under the proposed control action decays exponentially or in negative power o{ time. Then, some examples are given to show that the nonlinear boundary control considered in this paper is efficient and practical. -
