An Empirical Model and Feedforward Control of Laser Powder Bed Fusion

ASME Letters in Dynamic Systems and Control, 2023
Abstract Reliable process control for the laser powder bed fusion process, especially at the melt pool scale, remains an open challenge. One of the reasons for this is the lack of suitable control-oriented models and associated control design strategies. To address this issue, this paper (1) identifies an empirical control-oriented model
