Global stabilization of an enlarged class of cascade nonlinear systems

Abstract
We present a new approach to design controllers for global asymptotic stabilization of cascade and feedforward nonlinear systems. First we give conditions for global stability and construct a continuously differentiable Lyapunov function for a class of uncontrolled cascade systems. We use this Lyapunov function to design globally asymptotically stabilizing feedback laws for controlled cascade systems and, by applying the method recursively, for feedforward systems.
