This paper deals with the extension to sampled-data stabilization of strict feedback dynamics of the Immersion and Invariance procedure proposed in Astolfi and Ortega [2003]. A direct digital approach is developed in two steps: first the target dynamics and immersion mapping are defined for the equivalent discrete-time model; then the control law is built to drive the dynamics towards the invariant manifold. A simulated example illustrates the performances.
