Abstract
Technical solutions are described for providing torque ripple compensation when a motor control system is operating in feedforward mode. An example motor control system includes a feedforward controller that receives a first current command corresponding to an input torque command, and receives a second current command corresponding to a torque ripple. The feedforward controller generates a voltage command based on the first current command and the second current command, the voltage command being applied to a motor.
