Abstract :
In this paper the problem of output feedback stabilizability for a class of MIMO discrete-time nonlinear systems is considered. The proposed solution is based on an ad-hoc separation assumption that could be satisfied for the class of nonlinear systems characterized to have the full vector relative degree and the drift-observability properties. Numerical results for the simple academic case of pendulum show the effectiveness of this approach.
