This paper considers the problem of the global finite-time stabilization for the high-order nonlinear systemswith unknown control directions. Due to the uncertainty of control directions, the paper analyzes all possibleconditions of the directions. The Lyapunov-based logic switching rule ensures that we can find the correct controldirections. The adaptive switching controller with a switching parameter which is to be tuned online guarantees thatthe derivative of Lyapunov function is less than a negative definite function and the closed-loop system is globallyfinite-time stable. The effectiveness of the proposed method is illustrated by an example.
