Observer backstepping for a class of nonminimum-phase systems

In this paper the stabilization of nonlinear nonminimum-phase systems is considered. In particular the observer backstepping design of Krstic et al. (1995) is extended to stabilization of a class of nonlinear systems in output-feedback form with linear unstable zero-dynamics.
