Busting Deadtime Compensation Myths

Update and bump: Here’s the recorded PID Deadtime Compensation demo/seminar (616Mb .wmv file download).

Here’s the PID Deadtime Compensation presentation (download):

Original post: Modeling and Control blog’s Greg McMillan resumes his demo/seminar (a.k.a. deminar) series this Wednesday, Oct 13, at 10am CDT/13:00 UTC. His topic will be Dead Time Compensator Myth Buster.

He’ll tackle the following myths:

  • Deadtime is eliminated from loop
  • Control is faster for existing tuning settings
  • Compensator works better for loops dominated by a large deadtime
  • An underestimate of the deadtime leads to instability (PID tuning rule)
  • An overestimate of the deadtime leads to sluggish response and greater stability (PID tuning rule)

Update 2: There’s a problem with the embedded video with two tracks of audio playing, so I’m removing it and providing links to archive site.
