Journal of Convex Analysis 14 (2007), No. 4, 767--784 Copyright Heldermann Verlag 2007 Affinity and Well-Posedness for Optimal Control Problems in Hilbert Spaces Elena Muselli Dip. di Matematica, Università di Genova, Via Dodecaneso 35, 16146 Genova, Italy muselli@dima.unige.it Quadratic optimal control problems in Hilbert spaces are considered. We show that well-posedness of problems without constraints for all desired trajectories is equivalent to affinity on the control of the dynamics in the abstract Cauchy problem. Keywords: Well-posed optimization problems, control problems in Hilbert spaces, infinite dimensional linear systems. MSC: 49K40, 49N10, 47B49 [ Fulltext-pdf (159 KB)] for subscribers only. |
