Ask Dr Bob: How can I find dead-time with the FOPDT model?
Video Transcript: Hello, I’m Bob Rice. And in today’s episode, we’re going to continue our discussion of the FOPDT model, and how you can use it to describe the…
Read MoreHow Do I Calculate Dead-Time?
Adults can learn a thing or two from children. That’s especially true when it comes to matters of time. Whereas adults view it as fashionable to show up to a social event 15 or more minutes late, children can’t wait to go and be a part of the action. When at a theme park adults typically their time strolling from place to place while children know that each minute of delay can cost hours longer in line. Simply put: When it comes to time every second matters. That viewpoint seems highly relevant to process control, control loop tuning, and calculating Dead-Time. Dead-Time is generally the model parameter that’s easiest to calculate when tuning a PID controller.

Non-Steady State (NSS) Modeling is the ability to calculate an accurate process model when the associated data is oscillatory, is noisy, or has extensive Dead-Time. It’s a highly valuable capability when tuning difficult PID loops, and it was pioneered by Control Station.
