PIDs explained?

Posted by Brian Boyle on June 28, 2011 at 6:38pm

hey folks.

I am truly sorry if i have missed this some where but is there an explanation of what PIDs are and what they do? i see a great deal of talk about them but i have not found a listing.

sorry if i am asking about something that is already explained but i didn't find it in any searches.

When I need to read up on what the pids do, I have a look at HappyKillmore's GCS. He's got all the descriptions laid out next to each one.

I found this that was really helpful on explaining what each one does. I dont remember if I found it here or somewhere else.

this wiki page explains PIDs:

PIDs are simple control theory equations that we all use to generate a response to a situation. They are actually very simple, but in practice take a long time to tweak and tune.
