Advanced Startup Automation in the Power Industry
At the 2018 Ovation Users' Group Conference, a power producer shared their story of how they improved their unit startups through the application of advanced technology. The US electrical power grid is evolving rapidly as it adds more renewable generation from solar...
Wireless Multi-Rate Model Predictive Control
Communications networks have become pervasive at many levels in control system architectures. As wireless networks and the Industrial Internet of Things become more common, the complexity and security requirements for these networks grows. Emerson's Felipe Fakir...
Model Predictive Control in Power Generation
Model predictive control in power generation was the subject of a 2017 Ovation Users Group presentation by Emerson's Ranjit Rao. Rajit opened comparing classical control with model-based control. In classical control, a proportional-derivative-integral loop is used...
Model Predictive Control Tips & Techniques Preview
Moving from the theoretical world of proportional-integral-derivative control to applying it successfully is a hurdle new process control engineers face. Once mastered, the next step might be in applying advanced process controls. Model predictive control, neural...
Optimizing the Ammonia Production Process
Author: James Gremillion One of the earliest applications of "computer control", a now archaic term, on an ammonia plant was done in 1969 by Weissenfelder and Shah of Borden Chemical and IBM respectively. They were able to implement advanced control schemes in 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...
ISA Process Control and Safety Symposium Presentations
Last week, the 2015 ISA Process Control and Safety Symposium took place in Houston, Texas. Leading experts from across our world of process instrumentation and control shared their wisdom to help advance the cause of safer, more efficient and more reliable operations....
Differences in Model Predictive Control Applications
One of the new things that we tried at last week's Emerson Exchange conference in Denver was to have our Emerson Exchange 365 community members submit questions for a Meet the Experts session panel on process control and optimization. The thread, questions and answers...
Process Control & Optimization Expertise in Action
We had several great questions come in from Emerson Exchange 365 community members for the Experts session on Process Control and Optimization. You can see the answers in the Emerson Exchange 365 community in the Virtual Q&A: Process Control >> REPLY to THIS...
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...
Controlling with Wireless Devices and MPC
Wireless standards for instrumentation go back to September 2007 when the HART Communications Foundation (now FieldComm Group) announced the official release of the HART 7 specification. This specification included the WirelessHART protocol. As we have chronicled in...
