Abstract: The robust stabilization of nonlinear uncertain systems is discussed The necessary and sufficient condition of its robust stabilization is given, and a class of uncertain systems is obtained, in which the bound of the robust stabilization is independent of the bound of its Liapunov function Finally, an example is given

Key words: nonlinear systems, Liapunov functions, robustness
