Published in 2025 at "AIChE Journal"

DOI: 10.1002/aic.70141

Abstract: This paper proposes an offset‐free model predictive control (MPC) framework for nonlinear systems modeled using neural network‐based nonlinear autoregressive models with exogenous inputs (NARX). To address plant‐model mismatch and ensure offset‐free tracking, the NARX model… read more here.

DOI: 10.1016/j.ceramint.2019.01.214

Abstract: Abstract Crystallization kinetics of lithium aluminosilicate glass powder has been investigated by model-free and model–fitting methods. Non-isothermal experiments were carried out using differential scanning calorimetry (DSC) to monitor crystallization behavior. Model-free activation energy has been… read more here.

Published in 2021 at "Frontiers in Psychology"

DOI: 10.3389/fpsyg.2021.736132

Abstract: The purpose of this study is to explore the impact of constraining class-specific residual variances to be equal by examining and comparing the parameter estimation of a free model and a constrained model under various… read more here.
