PID Options and Solutions Part 3
This is the third and final part of the ISA Mentor series of WebEx presentations on PID Options and Solutions. In it, Greg McMillan describes simple tuning methods and the PID features that can be used to prevent the oscillations that plague our most important loops and to achieve the desired degree of tightness or looseness in level control. A general procedure is offered and a block diagram of the most effective PID structure, not shown anywhere else, is given followed by questions and answers.
PID Options and Solutions Part 2
Part 2 provides a quick review of Part 1 and then discusses: the contribution of each PID mode, why reset time is orders of magnitude too small for most composition and temperature loops, the ultimate and practical limits to control loop performance, the critical role of dead time, and when PID gain that is too high or too low causes more oscillation.
PID Options and Solutions Part 1
This is Part 1 of a series on the benefits of knowing your process and PID capability. Part 1 focuses on process behavior, the many loop objectives and different worlds of industrial applications, and the loop component's contribution to the dynamic response.
Loop Tuning and Optimization
In this ISA Mentor Program presentation, Michel Ruel, a key program resource and president of TOP Control, provides insight and guidance as to the importance of optimization and how to achieve it through better PID control. Ruel explains how optimization enables the plant to get the most out of its assets and how to reduce loop variability to achieve savings from less maintenance and closer operation to optimums. Ruel emphasizes the need to find and fix process and automation system design and installation problems before tuning the PID. He shows how to determine common detrimental characteristics of valve response, such as backlash and stiction, as well as offering extensive insight on the importance of loop dead time to provide effective estimates of the PID execution time, filter time, derivative time, integral time, and settling time by factoring the dead time. Different tuning rules are offered and the important benefits of simulation and software are illustrated. Ruel's extensive practical experience in improving control loops is evident throughout the presentation.
Barriers to Realizing the True Value of Automation
Peter Martin describes four barriers to realizing the true value of automation and a process for identifying the benefits and bottom line value of automation and control.
Batch Processes—Unique Challenges and Opportunities
Batch processes pose unique challenges and opportunities. Proper understanding of the difficulties faced and the new technologies and techniques offered can lead to solutions by better automation and control that offer much greater increases in efficiency and capacity than usually obtained for continuous process.
This presentation by ISA Fellow Greg McMillan starts with a discussion that gives expansive and deep insight not offered in the literature as to why batch processes are so difficult. The presentation then goes into how to analyze batch data, elevate the role of the operator, tune key control loops, and set up simple control strategies to optimize batch operations. The presentation concludes with an extensive list of best practices.
Automation War Stories: Lessons learned from the field
Listen to ISA members Greg Lehmann, technical manager for AECom Technology Corp., Denver, CO, and Jim Garrison, senior specialist, aeSolutions, Greenville, SC, share their real-life experiences and the lessons learned at a gas pipeline compressor station and in a biofuels feedstock plant, respectively.
Inside Automation: Theory Meets Reality 2015
ISA and MAVERICK Technologies held a jointly developed, high-level, invitation-only conference called Inside Automation: Theory Meets Reality in April, 2015. Thirty-five of the brightest minds in industry gathered in Columbia, Illinois, for an intensive 2-day workshop focused on creating a dialogue around some of the greatest challenges and opportunities that our industries face.
MAVERICK CEO and Founder Paul J. Galeski, P.E., CAP, delivered presentations on Developing Tomorrow’s Workforce and The Future of Automation, and Dr. Peter Martin, VP of Business Value Solutions for Schneider Electric, delivered a dynamic keynote address entitled “Unlocking the Value of Automation.” Below are three video clips from Dr. Martin’s keynote address.
What is the value of what you do?
Peter Martin, PhD, Vice President, Business Value Solutions, Schneider Electric
When Peter Martin was a kid, his father said to him “don’t try to solve world hunger”. That meant: Don’t take on a problem that’s too big to solve within the constraints that you’re given, says Martin. Automation and controls applied effectively can apply to the great challenges of the problems today. But what do we need to do? What is our value in the world today?
Back to the future
Martin recaps 30 years’ worth of how industry has come up with new technology looking for a problem. Where does that get us? Find out why technology is not the problem anymore.
Operational efficiency model
Martin discusses the operational efficiency model and how this model works; however, plants can be running efficiently but still not be profitable. What is the real problem?
Martin explains how you can utilize industrial control systems more efficiently and face the challenges of an ever-changing global marketplace in these informative resources:

What Is Automation?
Cleveland Community College explains what automation is all about.
