When a variability problem emerges in a production process, the first suspect is often to look at the tuning of PID [proportional-integral-derivative] loops. While adjustments can be easily made in most automation systems, this is often not the source of the problem. In an ISA Intech article, Know when to look outside the PID tuning, […]

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 […]

I heard a great story about a resins manufacturer who was having some issues in meeting quality specifications due to temperature variability in the process. Emerson’s Gergo Kertesz, whom you may recall from an Emerson Exchange presentation I liveblogged, shared this story. This variability not only impacted the quality of the produced resin, it impacted […]

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 co-presented a paper, Solve Control Loop Problems […]
