As electrical power producers and cogeneration facilities must handle the load swings produced on the supply and demand side. Optimizing steam temperature control is one key way to improve the reliability of on boilers and heat recovery steam generators (HRSGs) caused by load swings. I caught up with Emerson’s Jeffery Williams who shared the details […]
The history of model predictive control (MPC) dates back to the early 1970s invented at Shell Oil and was known as Dynamic Matrix Control. MPC was designed at that time to solve largescale control challenges. As technology advanced, this technology could be more widely applied on smaller-scale challenges. At this past 2019 AIChE Spring Meeting, […]
Today is the final day of the 2018 Emerson Exchange conference. The last session I’m attending is on Control Performance with Emerson’s James Beall, Courtney (Eddie) Lane, Dirk Thiele and Aspentech’s Alex Kalafatis. After the panel introduced themselves, Dirk opened the panel with a poll question, “How would you rate the overall control performance in […]
Emerson’s Laurie Ben and James Beall presented How to Sell the Value of Digitalization with MPC at the 2018 Emerson Exchange conference. Laurie opened by describing different ways digitalization is described—Industrial Internet of Things, Industry 4.0, and Digital Transformation to name a few. These technologies can help meet new regulation, keep up with the increasing […]
Emerson’s Mircea Lupu shared his thoughts on Ovation system algorithms for handling processes with long lag times—a control challenge that vexes many. Mircea opened noting that control algorithms are at the heart of any control system to provide stable and accurate response and robustness against disturbances and process changes. Tuning these algorithms to achieve the […]
