An observer‐based controller strategy for the asymptotic output tracking of a class of nonlinear systems is proposed. The generalized observability canonical form (ℱ) introduced by Fliess, is the main ingredient in our approach. Our tracking controller actually achieves uniform asymptotic stability by linearizing the tracking error. Two examples are considered to illustrate the effectiveness of the suggested approach.
