Re: Source code for PID

Hi, Martin,

Are you SURE you really want a PID controller?  There are many
other control technologies (bang-bang, SPC, etc.) -- each has
characteristics suitd to different types of control problems.

And, even if you *think* you want a PID controller, are you sure
ou need all three terms (i.e. P and PI controllers are far more
commonplace).

You'll also need to learn the basics about PID controllers if
you ever expect to deploy anything non-trivial.  I.e., tuning
can be a real chore.  And, there are many ways the controller
can "fail" (to perform adequately) if not designed well
(e.g., bumpless transfer, anti-windup, etc.)

Do yourself -- and your project -- a favor and research control
theory before trying to *apply* that theory...  :-/

HTH,

It would be nice if it also includes software which will help tuning the PID
loop.
I may also consider self tuning algorithm.

I consider to include it in our RTU (remote terminal unit) 
.
