Abstract :
This paper deals with the problem of global asymptotic stabilization for nonlinear systems with structural uncertainty and ignored input dynamics. A new characterization of control Lyapunov function is presented. Based on this characterization, a sufficient condition for the globally asymptotical stability is acquired and a state feedback control law is designed to globally asymptotically stabilize the equilibrium of the closed system. Last, the simulation shows the effectiveness of the method
