Abstract :
The global robust output regulation problem for nonlinear systems in output feedback form has been solved under a key assumption that the high-frequency gain sign is known. This note shows that this assumption can be removed by incorporating the Nussbaum gain technique into the existing framework for handling the robust output regulation problem.
