Abstract
Torque ripple produced by a traction motor of an electric vehicle when the motor produces torque from a motor current is compensated for by modifying operation of the motor according to a difference between an expected position of the motor to produce a desired torque from the current and the actual position of the motor when producing torque from the current.
