A system for reducing torque disturbance includes a motor mechanically
coupled to an endless belt. The motor is operable to drive the belt, and
the belt has a seam that causes a torque disturbance to the system. The
system includes a data structure having a set of values that indicates an
amount of compensation for reducing the torque disturbance and a
controller electrically coupled with the motor. The controller is
configured to control the motor and reduce the torque disturbance based
on the set of values in the data structure.
