Abstract:We investigate necessary and su?cient conditions under which a nonlinear afine control system with outputs can be written as a gradient control system corresponding to some pseudo-Riemannian metric defined on the state space. The results rely on a suitable notion of compatibility of the system with respect to a given afine connection, and on the input-output behavior of the prolonged system and the gradient extension. The symmetric product associated with an afine connection plays a key role in the discussion
