1. A motor control system for controlling operation of a motor, wherein:
the motor includes
a stator including one of an armature winding and a field winding, and
a rotor including another of the armature winding and the field winding;
the motor control system includes
a first inverter that supplies an armature current to the armature winding,
a second inverter that supplies a field current to the field winding, and
a control device that controls operation of the first inverter and the second inverter; and
the control device is configured to execute harmonic superimposition processing that at least partially cancels out harmonics appearing in the motor by superimposing a harmonic current on the field current, based on a motor operation index that indicates the operation of the motor.
