摘要：

This paper represents a simple attempt in connecting two basic concepts in classical system theory: sensitivity and controllability. More precisely, the controllability of the system which generates the sensitivity coefficients of any fixed and finite order, a sensitivity system, of a given linear system is here considered. According to the assumptions made on the dependence of the given system upon a vector of parameters, three simple sufficient conditions for the uncontrollability of the sensitivity system are derived. Such conditions involve only the dimensions of the state, control, and parameters vectors of the given system, and they allow the following conclusion: the sensitivity system is always uncontrollable, provided that the number of the parameters be sufficiently large. This paper is essentially a revised version of Ref. [1] containing slightly more general results. © 1969.
