Abstract :
Robust global stabilization of a class of cascaded systems with input unmodeled dynamics is considered by output feedback. The admissible unmodeled dynamics is assumed to be relative degree zero and input-to-state stable. A high-gain observer with an additional parameter is employed to cancel the affects of the unmodeled dynamics.
