Abstract :
An output feedback design technique is presented, by means of which it is possible to achieve semi-global practical stabilization for a class of non-minimum phase nonlinear systems, subject to parameter uncertainties. This work is an extension of the result by (Isidori, 2000). It provides a constructive controller design method for an auxiliary system, whose existence is crucial, but is assumed in (Isidori, 2000). Simulation results demonstrate satisfactory stabilization performances.
