Abstract
A current command value calculating unit () calculates current command values for a rotor winding () and current command values for a stator winding () with respect to a torque command value between a first rotor () and a second rotor () and a torque command value between a 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 first and second magnetic interference models. The first magnetic interference model represents a relationship of a linkage magnetic flux Φof the rotor winding () with respect to a current Iin the rotor winding () and a current Iin the stator winding (). The second magnetic interference model represents a relationship of a linkage magnetic flux Φof the stator winding () with respect to the current I, I.
