A colleague passed along the June edition of Control magazine with a marking on page 34 in their All Around Loop Controllers resource guide section.
It had a Tuning Tips Newsletter section courtesy of Emerson’s Educational Services group.
The page is put together by John Egnew, a Training Consultant and Instructor for Emerson Process Management. John’s purpose with these loop tips is to provide a compilation of years of experience with loop devices and controller tuning necessary for keeping control loops operating at the desired performance levels.
At the time of this writing there are six loop tips including:
- Do you always trust your flights to auto pilot?
- Is something dead in your loop?
- Do you understand your process?
- The Sticky Wicket Valve
- Getting tired of trial and error tuning?
- A Bigger Valve Is Not Always Better
John invites requests for more information, so send him an email, or add a comment on this post, and I’ll pass it along to John and invite his comments back.
The All Around Loop Controllers resource guide page also highlights Greg McMillan’s Good Tuning: A Pocket Guide, 2nd Edition book which is available in the DeltaV Bookstore and Process Control Video Training also available from Educational Services.
