Okay so this year, we're going to try to incorporate a PID loop to ensure that our shooter is spinning at the speed we want it to with little tolerance.
We're using a photoelectric sensor as a gear tooth counter, to calculate the RPM the shooter wheel is spinning. how can we convert this to %?
I've looked at the Velocity PID vi from The Fighting Pi (
http://www.fightingpi.org/Resources/Controls.shtml), but I have no idea how to tune the PID loop, or how to integrate it in our system. Some help would be appreciated.
