PID (Proportional-Integral-Derivative)-based control has been commonly used for decades. And while it still is adequate for controlling many process parameters, the time may be right to take a step back and re-evaluate PID-based control in power generation and other...

Driving Manufacturing Performance Gains with Cloud-based Optimization
The U.S. National Science Foundation (NSF) is: …an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..." In 2006, the NSF funded a...
Divided Wall Column MPC Control with Wireless Instrumentation
Distillation is an important process from crude oil refining to fine sipping whiskey production. Managing this process safely, efficiently and reliably is the challenge. In a recent Hydrocarbon Processing article, Use model predictive control to achieve real-time...
Wireless Event-Based Control
As wireless communications technology continues to mature, applications have expanded from monitor only to monitor and control. In an earlier post, Event-Based Control in a Wireless World, I mentioned that presentations given by Emerson’s Terry Blevins and Willy...
Methodology for Solving Control Loop Problems
This time of year, after our big Emerson Exchange conference, I like to go back and see what sessions I missed to be able to be able to recap for you. I caught up with Emerson's Mark Coughran, whom you may recall from many control performance-related posts. He...
Getting up and Running Quickly
Emerson's Gergo Kertesz shared a story of how to get a plant started up and running with the aid of control loop tuning. His abstract: This Russian Petrochemical Company is one of the world's largest petrochemical complexes. The company specialises in the production...
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...
Wireless Measurements in Control Applications
As wireless technology continues to be used in process manufacturing facilities, those used in control applications are increasing. At the ISA Automation Week conference, Emerson's Terry Blevins, Mark Nixon, and Marty Zielinski authored the paper, Using Wireless...
Lambda Control-Loop Tuning Essentials with James Beall
Having trouble with an oscillating integrating process? Have too much variability in a self-regulated process? Need a refresher about the essentials of Lambda (λ) tuning? Then check out James Beall's workshop at the Jan. 21–23 Texas A&M University 2014...
Process Automation System Design Techniques
For an automation project, what design methodology should you follow? Emerson's Scott Turner provides some thoughts for your consideration. When designing a new control scheme or strategy it is easy to underestimate the amount of design effort required.A well-designed...
Process Simulation to Test Compressor Anti-Surge Control Strategy
Some of our most consistently popular posts here at Emerson Process Experts center on anti-surge control for centrifugal compressors. I had the opportunity to catch up with Emerson's Ashish Patki when he was in town last month. Ashish shared a story where a national...
A Unified PID Control Methodology
PID control is the workhorse of process automation. At this week's AIChE 2013 Spring Meeting and 9th Global Congress on Process Safety, Control Talk blog's Greg McMillan and Eastman Chemical's Héctor Torres presented their paper, A Unified PID Control Methodology to...
