Abstract : Second order systems whose drift is defined by the gradient of a given potential are considered, and minimization of the L 1-norm of the control is addressed. An analysis of the extremal flow emphasizes the role of singular trajectories of order two [25, 29]; the case of the two-body potential is treated in detail. In L 1-minimization, regular extremals are associated with controls whose norm is bang-bang; in order to assess their optimality properties, sufficient conditions are given for broken extremals and related to the no-fold conditions of [20]. An example of numerical verification of these conditions is proposed on a problem coming from space mechanics. Keywords. L 1-minimization, second order mechanical systems, order two singular trajectories, no-fold conditions for broken extremals, two-body problem MSC classification. 49K15, 70Q05
