Some of my favorite posts are ones that come out of a string of problem-solving email messages. And so it is with today’s post. Emerson’s Mark Coughran was recently at biopharmaceutical facility that was having temperature control issues on a reactor vessel. The temperature process variable was overshooting far past the setpoint with the control […]

This interesting question was posed in the LinkedIn Process Control group. You’ll need to join this 31,000+ member group to see it, but the exact question was: Process Control Tuning – is not just science but an art. The real talent to be process control engineer lies in the fact how deep he understands the […]

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 non-self-regulating or integrating processes. Everything you probably learned about […]

Chris Womack here again with another guest post. 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 Instrumentation Symposium. James was kind enough to give […]

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 Meet Plant Objectives. Here is the presentation:
