Semi-global output feedback stabilization of a class of non-minimum phase nonlinear systems

We solve the problem of semi-global output feedback stabilization of a class of non-minimum phase nonlinear systems using a full order Extended Kalman Filter-Extended High Gain Observer proposed in [1]. We allow for any globally stabilizing full state feedback control scheme to be used as long as it satisfies a particular ISS condition. The proposed output feedback control system strategy is constructive and simple. Finally, we provide an example that illustrates the procedure and efficacy of the control design.
