Optimizing Sequence-Based Control Strategies
Update and bump: The whitepaper, DCS Controller Loading Reduction for Sequence Logic - A Boiler Control Project Case Study, is now available. Original post: Let's close this week with a post about sequence control loading improvements in boiler operations. I managed...
Three Tough Level Control Challenges
Emerson's Sergei Kuznetsov will be presenting at the rapidly approaching Emerson Exchange Technical Conference. In his presentation, Three Non-conventional Level Control Applications, Sergei shares how to approach three quirky level control challenges: Particle bin...
PID Control for Loops with Wireless Measurement and Final Control Elements
The ever-prolific Greg McMillan is at it again with an article, Wireless - Overcoming challenges of PID control & analyzer applications in the July/August edition of Intech. His article concludes: Wireless and composition measurements offer a significant...
Precise Continuous Pulse Output Control
I like to use the application TweetDeck first thing in the morning to quickly scan Twitter posts from the trade press and trade analysts, #PAuto (the established hashtag for "Process Automation"), Emerson folks and brands, and specialized searches on DeltaV, Emerson,...
Start with Desired Operator Actions in Alarm Strategy Development
Let's close this week with another great question and a great answer, this time involving operator alarm strategy development. A paraphrased version of the question was: I am planning to implement the on-delay / off-delay and deadband alarm parameters. Is there a...
Free Series of Greg McMillan Live Process Control Seminars and Demos
We're launching a new experiment in our world of process automation. I'm teaming up with process automation hall of famer, Greg McMillan, as he launches a series of live seminars and demos over the coming months. Greg has been sharing his process control and process...
Do You Know Your Manual Valve’s Position?
I don't want to admit how long I've know Emerson's Kurtis Jensen, but it does goes back to the pre-Emerson days at Fisher Controls. Kurtis is an instrument product manager for the Fisher Valve and Valve Automation businesses. He's penned a great article for Valve...
Applying Adaptive Control to Difficult Level Control Applications
As we get further away from our college years, sometimes misconceptions can solidify. For instance, most engineers that had a basic control theory class may recall that increasing the gain in a feedback loop at some point will introduce instability/oscillations. The...
Improved Distillation Column Recovery and Reduced Energy Usage
Here's another great presentation from the recent Emerson Exchange from refining & chemicals industry solutions director, Pete Sharpe. You may recall Pete from earlier process optimization-related posts. His presentation, SmartProcess Distillation Application...
Tips When Using DeltaV PID Control
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...
Applying Advanced Process Control to Distillation Processes
For those attending the Emerson Exchange with distillation processes, you don't want to miss Emerson's Lou Heavner's presentation, Advanced Distillation - 102. Lou is an advanced control consultant, whom you may recall from earlier posts. He'll be presenting Wed, 9/30...
