Adaptive Primal-Dual Method for Safe Reinforcement Learning

no code implementations1 Feb 2024 Weiqin Chen, James Onyejizu, Long Vu, Lan Hoang, Dharmashankar Subramanian, Koushik Kar, Sandipan Mishra, Santiago Paternain

In this paper, we propose, analyze and evaluate adaptive primal-dual (APD) methods for SRL, where two adaptive LRs are adjusted to the Lagrangian multipliers so as to optimize the policy in each iteration.

Control-Oriented Modeling and Layer-to-Layer Spatial Control of Powder Bed Fusion Processes

no code implementations8 Sep 2023 Xin Wang, Bumsoo Park, Robert G. Landers, Sandipan Mishra, Douglas A. Bristow

However, due to inherent process variability, it is still very costly and time consuming to certify the process and the part.

A Learn-and-Control Strategy for Jet-Based Additive Manufacturing

no code implementations7 Jul 2022 Uduak Inyang-Udoh, Alvin Chen, Sandipan Mishra

This approach is applied for feedforward predictive control in which the network parameters are learned offline from previous data and the control input pattern for all layers to be printed is synthesized.

An empirical model for feedforward control of laser powder bed fusion

no code implementations24 Jan 2022 Aleksandr Shkoruta, Bumsoo Park, Sandipan Mishra

The empirical model of this behavior is developed and validated on different geometries at different laser power levels.
