PIDLOOP API Documentation


#1

Hi,
I’ve done searches in this forum, and the wiki, but I can’t seem to find the documentation for PIDLOOP.h.

I’ve gone through the header, and I’m sort of sure I understand it, but it’d be nice to take out all doubt! :slight_smile:

(edit) PS: Just what exactly does ‘PID’ stand for? I’m pretty good at English, but not perfect.

TIA,
Michael

Hello Michael,
PID stands for Proportional, Integral and Derivative. There is lots of information on the web.

It’s used extensively in robotics and other dynamic systems. We also posted some information here on how PID loops are tuned:

Hope this helps!

Edward, thank you for linking to this tutorial. It is helpful. If anyone is looking for another tutorial, Adafruit has one on their site as well. It uses the original pixy, but not much changes with the PID loops.
