Note! These coefficients will always be ordered in the following way: kP, kI, kD, kF. Omission of values will drop up to the last value kP for a PController, however, do note in a PD controller the second term will be kI, not kD. PID/PD/P controllers are simply PIDF controllers with omitted values.
When using a CompositeController, do note you will have to supply all four coefficients to preserve ordering with the new composed controller.
