Geometry-Based Process Adaption to Fabricate Parts with Varying Wall Thickness by Direct Metal Deposition
(2019)Lecture Notes in Mechanical EngineeringThe process of direct metal deposition gains recently high attention in the additive manufacturing community, but its capabilities to fabricate complex geometries is still limited. Especially for thin-walled structures, heat accumulation can disturb the process significantly. An adaption of process parameters, for instance by a semi-empirical model, is able to stabilize the process. Herein, an algorithm is proposed that creates a digital ...Conference Proceedings -

Deep Value Model Predictive Control
(2019)In this paper, we introduce an actor-critic algorithm called Deep Value Model Predictive Control (DMPC), which combines model-based trajectory optimization with value function estimation. The DMPC actor is a Model Predictive Control (MPC) optimizer with an objective function defined in terms of a value function estimated by the critic. We show that our MPC actor is an importance sampler, which minimizes an upper bound of the cross-entropy ...Conference Proceedings -
