### Abstract

This paper is concerned with optimal control problems for an impulsive system of the form {Mathematical expression} where the measurable control u(·) is possibly discontinuous, so that the trajectories of the system must be interpreted in a generalized sense. We study in particular the case where the vector fields g_{i} do not commute. By integrating the distribution generated by all the iterated Lie brackets of the vector fields g_{i}, we first construct a local factorization A_{1}×A_{2} of the state space. If (x^{1}, x^{2}) are coordinates on A_{1}×A_{2}, we derive from (1) a quotient control system for the single state variable x^{1}, with u, x^{2} both playing the role of controls. A density result is proved, which clarifies the relationship between the original system (1) and the quotient system. Since the quotient system turns out to be commutative, previous results valid for commutative systems can be applied, yielding existence and necessary conditions for optimal trajectories. In the final sections, two examples of impulsive systems and an application to a mechanical problem are given.
