This paper studies the output feedback stabilization for nonlinear one-dimensional wave equation under boundary output with disturbance. Firstly, a time varying gain extended state observer is designed in terms of output to estimate disturbance. Secondly, the output feedback controller is obtained by the principle of interference compensation. Finally, the existence and uniqueness of the classical solution of the closed-loop system is proved and the asymptotical stability of the closed-loop system is obtained by the energy perturbation method by us.
