Global Asymptotic Stabilization for Nonminimum Phase Nonlinear Systems Admitting a Strict Normal Form

International audienceIn this paper, we address the problem of global asymptotic stabilization by output feedback for nonminimum phase nonlinear systems which admit a strict normal form. We assume the knowledge of an observer and, depending on its properties, we propose various approaches to design the control law. Each of these approaches needs a different stabilizability assumption on the inverse dynamics. In this way, within a unified framework, we recover and extend some already published results and we establish new ones
