1. A motor control system for determining, comprising:

  • a motor having a plurality of motor harmonics and a motor frequency; and

    a bandwidth compensation controller in communication with the motor, the bandwidth compensation controller configured to;

    determine a magnitude response compensation value and a phase compensation value for each of the plurality of motor harmonics, the magnitude response compensation value and the phase compensation value both based on the motor frequency; and

    determine a ripple compensating current based on the magnitude response compensation value and the phase compensation value.
