Event-Based Control in a Wireless World
The First International Conference on Event-Based Control, Communication, and Signal Processing was held June 17-19, 2015 in Krakow, Poland and took place on the campus of AGH University of Science and Technology. Some of the world leaders in Event-Based Control...
Contrasting Advance Regulatory and Advanced Process Control
I wanted to bring additional visibility to a great thread in the LinkedIn Process Control group on advanced regulatory control versus advanced process control. The post, So, ARC Can "Replace" APC? is based on a blog post, Advanced regulatory versus model-predictive...
Optimizing Delayed Coker Operations with Advanced Process Control
A refinery produces many products, one of them petroleum coke. AFPM defines it: Petroleum coke (petcoke) is one of many valued consumer products produced during the oil refining process. Crude oil is processed into gasoline, diesel fuel, jet fuel, lubricating oils and...
Distillation Column Control Basics – Part 3
Part 1 in the series addressed basic distillation column control and Part 2 explored inferential composition measurement and control design. In today's post I share how we need to consider how to close the material balance and the application of advanced process...
Adjusting Model Predictive Controller Response
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...
Regulatory and Model Predictive Control Difference?
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...
How Good is Your Level Control?
So asks Emerson's Lou Heavner in a thought-provoking post in the DeltaV track of the Emerson Exchange 365 community. Lou opens: Is it good enough? Is it too good? Do you even know? Should you care?Well yes, you probably should care. Most level processes are...
Applying Lambda Tuning to Six Common Control Challenges
Last year, some controversy broke out in the process automation and control community about the use of Lambda tuning for proportional-integral-derivative (PID)-based control. In a post, Lambda Tuning-Yeah or Neah?, we offered a differing view to a Control magazine...
With Smart Process Distillation, James Beall Finds Hidden Savings for Gulf Coast Plastics Plant
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...
Sharing Process Control Expertise with Next-Gen Automation Professionals
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...
Making Advanced Process Control Practical
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...
