Abstract: This paper studies the robust practical output tracking problem using a dynamic output feedback controller (called an output compensator) for a family of uncertain inherently non-linear systems in the p-normal form of a particularly complex nature such that their linearisation around the equilibrium state may be unstabilisable and/or undetectable. It is shown that under some mild conditions on such a given system, it is possible to construct an output compensator achieving the robust practical output tracking and such a compensator is explicitly constructed by the coupled controller-observer design methods recently proposed. The usefulness of the result obtained is illustrated by a simple numerical example.
