P4FPID: A Toolbox for Direct and Advanced Interactions With Fuzzy Logic Controllers With an Application to a Ball‐and‐Beam System

Computer Applications in Engineering Education, Volume 34, Issue 6, November 2026.
ABSTRACT Fuzzy logic control is well known for its robustness across various automation engineering applications. Its structured linguistic modeling of human expertise and empirical knowledge makes it attractive to both students and control engineers. However, such expertise can only be developed through practice and trials. Existing solutions are time‐

A perspective on parsimonious hybrid models for online use: Augmenting fundamental models with ARIMA disturbances

The Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5854-5874, November 2026.
Abstract Hybrid models (HMs) combine fundamental model (FM) equations with empirical components. These models can lead to improved predictions because they reduce process/model mismatch and can account for phenomena that are not considered in the FM equations.
