Abstract
A simple condition for the output reproducibility of a given trajectory, and an associated control law, are derived on the basis of the zero-dynamics algorithm. If the output reproducibility condition is not satisfied and/or uncertainties are present, sliding control is shown to perform asymptotic tracking whenever the zero-dynamics of an extended system, related to the given system and to the reference trajectory, satisfies some stability properties. The choice of an appropriate sliding surface is inferred from the inversion algorithm
