Abstract :
This correspondence deals with the controllability of the sensitivity system associated to a given linear discrete system. It is proved that, apart from exceptional cases, the sensitivity system is always uncontrollable provided that the number of the parameters is sufficiently large. The results presented here have a structural nature since they involve only the dimensions of the state, control, and parameter vectors.
