1. An information processing device that calculates a current command value based on a torque command value of a rotary electric machine, whereinthe rotary electric machine comprises a first rotor in which a rotor winding is provided, a stator in which a stator winding is provided, and a second rotor that opposes the first rotor and the stator and that is rotatable relative to the first rotor,a torque acts between the first rotor and the second rotor according to a magnetic flux due to a current in the rotor winding acting on the second rotor, and a torque acts between the stator and the second rotor according to a magnetic flux due to a current in the stator winding acting on the second rotor,a linkage magnetic flux of the stator winding can be adjusted by the current in the rotor winding and a linkage magnetic flux of the rotor winding can be adjusted by the current in the stator winding,the information processing device comprises a current command value calculating unit that calculates a current command value for the rotor winding and a current command value for the stator winding with respect to a torque command value between the first rotor and the second rotor and a torque command value between the stator and the second rotor, based on an evaluation function representing a total copper loss of the rotor winding and the stator winding and using a first magnetic interference model and a second magnetic interference model,the first magnetic interference model represents a relationship of the linkage magnetic flux of the rotor winding with respect to the current in the rotor winding and the current in the stator winding, andthe second magnetic interference model represents a relationship of the linkage magnetic flux of the stator winding with respect to the current in the rotor winding and the current in the stator winding.
