* Revolutions read via. back EMF.
* Simple PI (proportional, integration) controller.
* 1 kRpm / V.
Notes:
Try changing the motor load in simulation, and watch the motor supply voltage change until the RPM is back in place.
You can also try changing the reference and see how the motor feedback follows.
