Knowledge sharing need not be limited to one week conferences like the recent Emerson Exchange conference. I mention this to highlight an excellent discussion thread in Emerson Experts Forum in the Emerson Exchange 365 community. The thread, MPC [Model Predictive...
Over in LinkedIn's Process Control group, a question was asked: What is the difference between regulatory and model predictive control. Is it possible that MPC work as stand alone without regulatory control? Emerson's Chowyang Neo offered: Regulatory Control generally...
Last week, Emerson Consultant James Beall was working with a major U.S. plastics facility on the Texas Gulf Coast, helping the firm figure out how it might save some of the money it spends on distillation energy by using Emerson's Smart Process Distillation Column...
One of the very active U.S. universities in the field of engineering and automation is Oklahoma State University. Their OSU Automation Society was founded several years ago and its purpose is to spread awareness and promote automation and control systems as a...
It's human nature to operate within a comfort zone. For plant operators, where the stakes are incredibly high, it means operating away from constraint limits. Unfortunately, to maximize the performance of the process, it means to get as close to the limits as you can...
A recent ControlGlobal.com article, Advanced Process Control Ain't Easy, concluded: The optimal solution is elusive, but perhaps the most promising path is to start with the simplest APC possible, one that delivers an acceptable percentage of theoretical benefits, but...
Emerson's James Beall presented Master the Mystery and Marvels of DeltaV MPC at the 2012 Emerson Exchange. His abstract: Have you found the perfect application for Model Predictive Control (MPC) but don't know how to get started? Or perhaps you have implemented an MPC...
In the process optimization category of this blog, we've described many examples of advanced process controls and how they help to improve plant performance. One of the leading providers of multivariable APC over the years has been Aspentech and their DMCplus...
I saw a tweet from Control magazine editor-in-chief Walt Boyes, which alerted me to a presentation that I needed to get my hands on. Emerson's Bob Sabin, a member of the industrial energy team, was kind enough to provide me a copy. You may recall Bob from several...
For U.S. refiners, the bulk of project spending is on core business drivers including safety, environmental performance, and reliability programs. Projects that optimize performance and improve energy efficiency often don't make the cut. At the AIChE National Spring...
I came across an interesting Emerson Exchange presentation, Model Predictive Control for Integrating Processes, by Emerson's Lou Heavner. You may recall Lou from several advanced control-related posts. Lou introduced the subject noting that historically, APC project...
ModelingAndControl.com's Greg McMillan is resuming his demo/seminar (a.k.a. deminar) series tomorrow, August 11, 2010. The subject will be reducing batch cycle time and startup time for true integrating processes through improved PID control. The deminar will begin at...
