Output regulation for a class of nonlinear systems using the observer based output feedback control

In this paper we study the global robust output regulation problem for a class of nonlinear systems by output feedback control. The class of systems possesses nonlinear zero-dynamics and, is thus considerably larger than systems studied in the existing literature. As an illustration of our approach, we have applied our approach to the global robust asymptotic tracking problem of the hyperchaotic Lorenz system.
