Emerson’s Greg McMillan and CMiD Solutions’ Mark Darby discuss the best practices in distillation column composition control strategies. Right from the opening of the part one article, you can get a good sense of the technical depth and experience shared by both Greg and Mark.
Here is a 5-part series on ControlGlobal.com by Process Automation Hall of Fame member Greg McMillan, The concealed PID revealed.
pH control can be extremely challenging due to exceptional nonlinearity and sensitivity particularly when strong acids and strong bases are used. Advances in electrode design and signal selection can greatly help. The need to reduce oscillations from valve resolution limit and backlash can be addressed by valve design and use of a PID feature.
At AIChE Spring21+17th GCPS, James Beall presented, An Activity Report on the Newly Formed ISA 5.9 Subcommittee on the PID Algorithm, to address the lack of no standards or technical references related to the Proportional, Integral, Derivative (PID) control algorithm.
Emerson’s Greg McMillan, teaming with Christopher Stuart, Rehman Fazeem, Zachary Sample and Timothy Schieffer have updated and revised the 2nd edition of the book, New Directions in Bioprocess Modeling and Control.
Control valve response is a critical factor in successful control strategies and process variability. In a ControlGlobal.com article, Responsible control valve response, Emerson’s Greg McMillan and James Beall discussed the efforts underway to include valve responsiveness into the ISA 75.25 Control Valve Dynamic Testing standard.
Greg McMillan’s presentation, Process Effects on Control explores how various process types affect objectives, tuning, and performance. Greg opened noting that control loops have many different objectives.
At Texas A&M University’s Mary Kay O’Connor Process Safety Center’s 76th Instrumentation and Automation Symposium, Emerson’s Greg McMillan presented on Bioreactor Control and Optimization using Digital Twin technology.
El mejor control de procesos en términos de habilidad para mejorar la eficiencia operacional y la capacidad, requiere un entendimiento de las relaciones del proceso y su efecto en las condiciones de operación establecidas por el sistema de automatización.
Greg McMillan presented at the AIChE Spring Meeting on the current state of automation engineering professionals and recommended solutions for advancing the profession.
One decade ago I collaborated with Process Automation Hall of Fame member, Greg McMillan to do a series of webinars on basics of process control.
I wanted to share this question and answer on setpoint lead-lag, from the Mentoring Engineers discussion group in the Emerson Exchange 365 community. The question: …one of the options you recommend for eliminating overshoot at setpoint changes is using a setpoint...
