Novice Pac Control PID questions

PAC Project
1

Hi!

First of all sorry for my english :frowning:

Iā€™m newbie using PAC Control. I had attached a zip file containing a sample strategy for a PID. The purpose of this strategy is not to use negative gain in PID and in some cases add a correction factor. I need to do this in fourteen PID. My question is whether the approach is correct? or is there a better way to do this?

Some blocks have been exaggerated for clarity of the example. I hope You understand

Hi fidel,

Welcome to the forums. You might want to contact PSG (our Product Support Group) for some FREE! help sorting this out.

Iā€™m curious, why are you trying to avoid a negative gain?

Thereā€™s a not-yet-complete video on PID that talks about ā€œnegative gain,ā€ hereā€™s a link to the snippet on that topic (click here).

Also, in case you havenā€™t seen these two (complete) PID videos, you might want to check out:

Kellyā€™s short (approx 6 minutes) intro video

Benā€™s archived webinar (almost 1 hour) on PIDs

This PID Tutorial might also be useful.
