How to force encoder values to equal a formula?
 

I'm using Labview to try to program a swerve drive. I need the encoder values to match up with one of my formula script. If you know how please reply.:confused:

i know i have to use PIDs, but are there any specifics or sugestions from anyone?

I think your original wording is a little confusing ... but I think I'm gathering your intent. You know where you WANT it to go (the formulas), but need tips on getting it to do what you want. Right?

... you don't "force encoder values". You vary the input controls to the motors and the encoders are the sensors that provide the feedback to our control loops.


There's a really good paper on PID by Tim Wescott ... called PID without a PhD. It'll get you started. Then keep asking questions. That's what we're here for.

ok we solved it (without that long pdf). now how do i close this thread?

Just leave it alone, don't water it, and the thread will die off naturally.

Bye!

(PS: That "long PDF" is one of the best papers on the topic of making something work with a PID loop. It actually might be worth reading. Even more if your system isn't doing what you expect it to do)
