[HTML][HTML] Transformed inputs for linearization, decoupling and feedforward control

S Skogestad, C Zotică, N Alsop - Journal of process Control, 2023 - Elsevier
This paper introduces powerful static input transformations which transform the original
system (process) into a transformed system which is easier to control. The transformed …

What is field theory?

JL Martin - American journal of sociology, 2003 - journals.uchicago.edu
Field theory is a more or less coherent approach in the social sciences whose essence is
the explanation of regularities in individual action by recourse to position vis-à-vis others …

A hybrid neural network‐first principles approach to process modeling

DC Psichogios, LH Ungar - AIChE Journal, 1992 - Wiley Online Library
A hybrid neural network‐first principles modeling scheme is developed and used to model a
fedbatch bioreactor. The hybrid model combines a partial first principles model, which …

A time scale-bridging approach for integrating production scheduling and process control

J Du, J Park, I Harjunkoski, M Baldea - Computers & Chemical Engineering, 2015 - Elsevier
In this paper, we propose a novel framework for integrating scheduling and nonlinear control
of continuous processes. We introduce the time scale-bridging model (SBM) as an explicit …

Nonlinear control strategies for continuous fermenters

MA Henson, DE Seborg - Chemical Engineering Science, 1992 - Elsevier
