ModelingAndControl.com‘s and Emerson technologist, Greg McMillan, will be presenting tomorrow at the ISA’s Boston section. His presentation, Exceptional Process Control Opportunities describes how advances in measurements, valves, and control can make a dramatic difference in important applications such as bioreactor, compressor, exothermic reactor, and neutralizer control. For those that can join this event, Greg has promised:

…giving out 10 free copies of my book The Funnier Side of Retirement for Engineers and People of the Technical Persuasion to balance out the serious stuff.

I asked Greg if I could upload his presentation to SlideShare.net, so that I could embed it here and share it with all of you. He graciously agreed. I’m also hoping social media maven, domesticatingIT blogger, and ISA Boston section president, Jon DiPietro, might have Greg’s words recorded so we can turn the presentation into a slidecast.

Some of the wide-ranging ground Greg covers in this presentation includes wireless measurement and control, sample time concepts, integrating processes such as batch processes, controller tuning, precision control valves for pH control, expertise retention and development, and open loop backup such as compressor surge and U.S. Resource Conservation and Recovery Act (RCRA) pH.

Greg also promises future blog posts for a whole lot of items he’s not able to cover including batch profile controls, adaptive feedback control and linearization, adaptive FeedForward control and linearization, full throttle set point response for batch and startup, controller output overdrive, dynamic reset limit, fast and intermittent disturbances and discontinuities, integration of loop, process, and maintenance data, root cause analysis, data visualization, virtual tool for learning and exploring opportunities, peak control. If you have interest in any of these topics you’ll want to subscribe to the blog’s RSS feed, if you’re not already subscribed.

Greg, being a prolific author extraordinaire, also points to a soon-to-be released work, Essentials of Modern Measurements and Final Elements in the Process Industry. He is donating the royalties from this book to the University of Texas Research Campus for Energy and Environmental Resources for development of wireless instrumentation and control.

If you’re in the New England-area tomorrow, here’s the event page to find out more details. If you’re not, look at the embedded presentation and see some of the wisdom Greg shares, particularly in the slide 22: Wireless PID Control Conclusions, slide 24: Sample Time Guideline Notes, slide 33: Integrating and Runaway Process Tuning, and slide 45: Best Practices to Improve Valve Performance.

Update and bump: I sat down with Greg on Friday and recorded an audio track of his presentation and synched it with the presentation to create a Slidecast.

Check out Greg’s findings beginning at slide 14 on how the the behavior of wireless PID control had less oscillations to wired PID control. It was somewhat of a surprising finding.
