We consider the problem of disturbance decoupling by means of a single state feedback for a whole family of systems depending on a parameter, p. We give a geometric necessary and sufficient condition for the existence of solution to such problem under the hypothesis that the systems of the family are generically injective and the dependence on p is polynomial or, respectively, the set of possible values for p is finite. © 1993.
