Abstract :
This paper studies the design of a full-order, high-gain observer for a class of minimum-phase nonlinear systems. The dynamic state feedback design is modified to include the observer for the internal dynamics. It is shown that the performance of such a dynamic partial-state feedback control can be recovered by the output feedback control using a sufficiently fast high-gain observer, in the presence of model uncertainty.
