Elaboration de stratégies de commande numérique pour une optimisation de la vitesse de parcours en fabrication additive

Abstract : In the field of additive manufacturing, one of the main objectives is the optimization of the production through maximization of machining speeds, regardless of the actuator and the power source deployed. In this framework, investigation of optimized control strategies for the actuators is a major issue. In this Thesis, we will place emphasis on the system which consists of galvanometer as actuators and laser as power source. In the galvanometer laser scanner context, current performance is limited by the unknown effects of the actuator dynamics on the laser spot position over time. It is necessary to master these actuator dynamics otherwise unoptimized timeouts are introduced, which slow down the machining process. Machining speeds can be enhanced through accurate modeling of the actuator dynamics. Works in this thesis consist in implementing accurate simulation environment of the actuator system and control strategies suitable to the additive manufacturing operation.
