Abstract :
A preliminary result on the construction of norm estimators for general nonlinear systems that do not necessarily admit a input output to state stable (IOSS)-Lyapunov characterization is given. Furthermore, an output feedback stabilization scheme is presented that makes use of norm estimators. This construction extends some previous results allowing for more general nonlinearities. Two examples complete the work.
