Box constraints for the controls are imposed and the cost functional involves the state and possibly a sparsity-promoting term, but not a Tikhonov regularization term. Unlike finite dimensional optimization or control problems involving Tikhonov regularization, second order sufficient optimality conditions for the control problems we deal with must be imposed in a cone larger than the one used to obtain necessary conditions. Different extensions of this cone have been proposed in the literature for different kinds of minima: strong or weak minimizers for optimal control problems. After a discussion on these extensions, we propose a new extended cone smaller than those considered until now. We prove that a second order condition based on this new cone is sufficient for a strong local minimum.", "revisions": [ { "version": "v1", "updated": "2019-05-14T07:14:27.000Z" } ], "analyses": { "subjects": [ "35K59", "49K20" ], "keywords": [ "sufficient second order conditions", "optimal control problems", "critical cones", "second order sufficient optimality conditions", "tikhonov regularization" ], "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable" } } }
