Generative AI and Process Systems Engineering: The Next Frontier

no code implementations15 Feb 2024 Benjamin Decardi-Nelson, Abdulelah S. Alshehri, Akshay Ajagekar, Fengqi You

This article explores how emerging generative artificial intelligence (GenAI) models, such as large language models (LLMs), can enhance solution methodologies within process systems engineering (PSE).

Computing control invariant sets of nonlinear systems: decomposition and distributed computing

no code implementations11 May 2022 Benjamin Decardi-Nelson, Jinfeng Liu

In this work, we present a distributed framework based on the graph algorithm for computing control invariant set for nonlinear cascade systems.

Sensitivity-based dynamic performance assessment for model predictive control with Gaussian noise

no code implementations5 Jan 2022 Jiangbang Liu, Song Bo, Benjamin Decardi-Nelson, Jinfeng Liu, Jingtao Hu, Tao Zou

To this end, a sensitivity-based performance assessment approach is proposed to pre-evaluate the dynamic economic and tracking performance of them in this work.

Robust economic MPC of the absorption column in post-combustion carbon capture through zone tracking

no code implementations5 Jan 2022 Benjamin Decardi-Nelson, Jinfeng Liu

To ensure that the zone tracking objective is achieved in the presence of model uncertainties and time-varying flue gas flow rate, we propose a method to modify the original target zone with a control invariant set.

Subsystem decomposition and state estimation of nonlinear processes with implicit time-scale multiplicity

no code implementations1 Oct 2021 Sarupa Debnath, Soumya Ranjan Sahoo, Benjamin Decardi-Nelson, Jinfeng Liu

In this work, we propose a subsystem decomposition approach and a distributed estimation scheme for a class of implicit two-time-scale nonlinear systems.

Robust economic model predictive control with zone tracking

no code implementations20 Sep 2021 Benjamin Decardi-Nelson, Jinfeng Liu

To optimize the economic performance within the zone in the presence of disturbances, we introduce the notion of risk factor in the controller design.
