For any strict feedforward system that is feedback linearizable we provide (following our earlier results) an algorithm, along with explicit transformations, that linearizes the system by change of coordinates and feedback in two steps: first, we bring the system to a newly introduced Nonlinear Brunovský canonical form (NBr) and then we go from (NBr) to a linear system. The whole linearization procedure includes diffeo-quadratures (differentiating, integrating, and composing functions) but not solving PDE’s. Application to feedback stabilization of strict feedforward systems is given.
