This talk concerns the adaptive fast finite time control of a class of nonlinear uncertain systems of which the upper bounds of the system uncertainties are unknown. By using the fast non-smooth control Lyapunov function and the method of so-called adding a power integrator merging with adaptive technique, a recursive design procedure can be obtained, which guarantees the fast finite time stability of the closed-loop system. I will prove that the control input is bounded under some weak conditions, and a simulation example will be given to illustrate the effectiveness of the theoretical results. This technique is motivated by the recent development of multiple-surface sliding mode control.
