Some of the more popular posts here on the blog involve loop tuning. Our Process Optimization category is filled with more than 150 posts featuring the wisdom of many experienced practitioners. One extremely proficient practitioner and prolific author, Greg McMillan...
The subject of process dynamics can get quite involved and cause many to shy away from it. Emerson's Felipe Fakir, a systems engineer based in Brazil, has written a whitepaper, Process Characterization, to make the topic more approachable—at least in how to identify...
Sometimes when you read an article about tuning proportional-integral-derivative (PID) loops, you're treated to all the 2nd order differential equations they contain. These can be intimidating, especially if your college calculus classes are many years in the rearview...
I received an interesting story from Emerson's James Beall about a process manufacturer with a process filled with many fermentors. They were being converted over from Provox control systems to DeltaV systems. pH control was a key part of the plant's fermentation...
Earlier this week, I highlighted a presentation by Emerson's James Beall, Fundamentals of Modern Loop Tuning. I shared his approach for tuning self-regulating loops and the sequence to tune interacting loops. Today, I'll share some guidance from the portion of the...
Update: The ControlLoopFoundation.com site is no longer operational. I've highlighted a few Emerson presentations for this week's ChemInnovations conference in New Orleans. Emerson's James Beall, a 30-year veteran in process control and chairman of the ISA 75.25...
Last week, I highlighted a narrated presentation on PID control advances by Emerson's Terry Blevins. Also at this IFAC Conference on Advances in Process Control PID'12, Terry presented Intelligent PID Product Design. A paper to complement this presentation was...
Greg McMillan resumes his demo/seminar (a.k.a. deminar) series this Wednesday, Oct 13, at 10am CDT/13:00 UTC. His topic will be Dead Time Compensator Myth Buster. He'll tackle the following myths: Deadtime is eliminated from loop Control is faster for existing tuning...
Last year I summarized an Emerson Exchange presentation by James Beall, Advanced PID Functions for Improved Control Performance. At this year's Emerson Exchange, he did a reprise version, Interesting and Useful Features of the DeltaV PID Controller. I'll highlight...
