On the output stabilization of nonlinear/uncertain systems

This paper considers the problem of stabilizing a class of dynamical systems with matched bounded nonlinearities/uncertainties. Stabilization is accomplished via feedback of the output, solely. The feedback stabilizing control is switching in nature and guarantees that the system is not only globally uniformly asymptotically stable but that the norm of the state vector decays exponentially to zero. A continuous version of this control is also offered as well as an illustrative example.
