I know there have been a ton of PID threads. But it is getting to be crunch time and I am sure that one more reference document will not go wasted.

I just came accross this simple paper from the great folks at www.embedded.com (http://www.embedded.com) :: PID Without a Ph.D. (http://www.embedded.com/2000/0010/0010feat3.htm)

I think it is a good introduction with many graphs and very good implementation details. An excellent How To.

I have pieced together a printer friendly version of the paper -- PM me (include your e-mail address) and I will shoot you a copy (it is 21 pages including 18 nice figures)*.

FYI

*I hesistate to upload it because it is not my work and I think the guys from embedded.com deserve the traffic. Am no lawyer but I think sharing a printer friendly version falls within so called "fair use." Again, just PM me and I will save you a few minutes of cutting and pasting.

I've had a pretty good grasp on what PID and how it works for a while, but I read this paper about a month ago and I learned alot more about the internal mechanics of the the control loop.

This is a very good tool, thanks for bringing attention to it Dr. Joe!

Good post!

For those of you who know a pack rat and long time subscriber to Embedded Systems Programming/Embedded Systems Design, the article was originally published in the October 2000 issue starting on pages 86.

Sadly, I fall into that category and could find it on my shelf.

Shame on Me!

I did not search first.

By the way, not only is does he post excellent messages, Mr. Shaul's has a great signature:

I am like a dog in this respect: I don't argue with Bacon ;-)

With that poor joke, I close this thread and refer folks to the thread earlier thread.
