Use a flywheel, and use Jag CAN Voltage mode or do voltage compensation in the cRIO

We are currently using PID and we are getting an oscillating error of about 5%.

First, look at the signal you are getting from your speed sensor (open loop) to make sure you are actually getting a clean signal.

Any ideas how to minimize this error

Read the several threads here on CD that discussed PID speed control of 2012 shooter wheels.

we are currently only using P
