An optimal control problem governed by heat equation with nonconvex constraints applied to selective laser melting process
Résumé
This paper deals with a PDE-constraints optimal control problem applied to an Additive Manufacturing process, namely a selective laser melting. Here, we want to control the temperature gradient inside the domain during a fixed time of heating, by acting on the trajectory of the dynamic Gaussian heating source. The non convex set of admissible controls reflects the fact that the control must fill the part of the boundary irradiated by the laser.
