Just curious why there is no derivative setting for tuning the PID loop. Was it found that it was not needed ?
I think a proper PID controller only works well when your set point and environmental conditions aren’t constantly changing. The way I understand it, adding D wouldn’t add much, if any, benefit. Even Integral isn’t used in the steer module, it’s pretty much Proportional only.
Yes I didnt think about the set point being a constant moving target. Id like to know what the big green and red systems use for there calculations. I dont think the user has as much input on those like we do.
In my experience from using a JD system in our combine, they know all the particulars of their own equipment (measurements, steering response rates etc) so they’re loading up those settings automatically. AOG is meant to work with a wide variety of configurations so then we need a lot of settings/options. Maybe someday we’ll have a community database of presets.
