Abstract
According to one or more embodiments, a motor control system that provides torque ripple compensation includes a current regulator that receives a first current command corresponding to an input torque command. The current regulator further generates a first voltage command based on the first current command using a first transformation matrix. The current regulator further receives a second current command corresponding to a torque ripple to be compensated. The current regulator further generates a second voltage command based on the second current command using a second transformation matrix. The current regulator further computes a final voltage command using the first voltage command and the second current command, the final voltage command being applied to a motor.
