Re: Teams: How did you use your potentiometers this year?

We used THREE pots to tune our PID loops.

run each one into an analog.

P = analog
I = analog
D= analog

Inside the software, they had to be mutliplied by 0.0001 I think...then the value of the pot was the P,I,D values. Made for a very fast tunable system. Used that in conjuntion with LABVIEW to graph the output...it worked out great.

I wish I could find a picture of the pots, but I can't. I do know our software is posted at frcsoft.com if you want to check out the software side of it. Once the tune was found, we hard coded the value into the software I think...I can't remember it's been too long...lol....
