Journal ArticleDOI
Machine learning-based predictive control of nonlinear processes. Part I: Theory
TL;DR: Machine learning ensemble regression modeling tools are employed in the formulation of LMPC to improve prediction accuracy of RNN models and overall closed-loop performance while parallel computing is utilized to reduce computation time.
Journal ArticleDOI
CFD modeling and control of a steam methane reforming reactor
TL;DR: In this article, a computational fluid dynamics (CFD) model of an industrial-scale steam methane reforming reactor (reforming tube) used to produce hydrogen was developed and three different feedback control schemes were evaluated to drive the area-weighted average hydrogen mole fraction measured at the reforming tube outlet ( x ¯ H 2 outlet ) to a desired set-point value under the influence of a tube-side feed disturbance.
Journal ArticleDOI
Machine-learning-based predictive control of nonlinear processes. Part II: Computational implementation
Journal ArticleDOI
Process structure-based recurrent neural network modeling for model predictive control of nonlinear processes
TL;DR: The proposed physics-based RNN models are utilized in model predictive controllers and applied to a chemical process network example to demonstrate their improved approximation performance compared to the fully-connected RNN model that is developed as a black box model.
Journal ArticleDOI
Real-Time Adaptive Machine-Learning-Based Predictive Control of Nonlinear Processes
TL;DR: A machine learning-based predictive control scheme that integrates an online update of the recurrent neural network models to capture process nonlinear dynamics in the presence of nonlinear forces is presented.
