Using an adaptive reduced-order observer for output feedback stabilization of uncertain cascade systems

Under the condition that the bounding system depends linearly on the unmeasurable states but nonlinearly on the systems output, we present a preliminary result on global adaptive stabilization via output feedback for a class of uncertain cascade systems with zero-dynamics, in the presence of parametric uncertainty. The result presented in this short note removes the polynomial growth condition imposed in the previous work
