The tuning of proportional-integral-derivative (PID) control loops was an important change at HollyFrontier’s Navajo Refinery in Artesia, N.M. Its hands-on, “mandraulic” culture was no longer cutting ...

Author Dr. R. Russell Rhinehart discusses his new book, Nonlinear Model-Based Control: Using First-Principles Models in Process Control, and explains why nonlinear first-principles models should be ...

At the core of any modern industrial process is a control system guaranteeing precision, stability, and efficiency. Perhaps the most commonly used are PID (Proportional-Integral-Derivative) ...

Aim: To demonstrate the potential of in-line nanoparticle size measurements using the NanoFlowSizer (NFS) as a PAT method. To achieve real-time process control by establishing automated regulation of ...

A few weeks ago, I installed an automatic water heater switch to my bathroom, but it was a crude device. What I really want to do is design a universal heater driver. That basic idea can be adapted to ...
