Error estimates in terms of the penalization parameter are stated. The results are compared with some previous ones in the literature and are checked by a numerical experiment. A detailed study of the regularity of the solutions of the PDEs is carried out.}, organization = {The first two authors were partially supported by Spanish Ministry of Education and Science under projects MTM2005-06817 and “Ingenio Mathematica (i-MATH)” No. CSD2006-00032}, publisher = {EDP Sciences}, publisher = {ESAIM: Control, Optimisation and Calculus of Variations, 2009, 15(4), 782-809}, title = {Penalization of Dirichlet optimal control problems}, author = {Casas Rentería, Eduardo and Mateos Alberdi, Mariano and Raymond, Jean Pierre}, }
