%X The finite-time stabilization is investigated for a class of zero-dynamics uncertain nonlinear systems, for which a practical adjustable settling-time controller is designed by using the Lyapunov theory of finite-time stability and the backstepping methodology. With the designed state-feedback controller, the closed-loop system is globally stable in a finite time with an adjustable settling-time. Especially, when the initial conditions are known, the settling-time can be arbitrarily adjusted. Simulation results are also given to illustrate correctness of the main results.
