A control device for a driving apparatus configured with a rotary electric machine having a rotor with a permanent magnet and a stator having a coil. A field adjusting mechanism is configured to change a field flux supplied by the rotor, and an inverter is connected to the coil. A field command determining portion is configured to determine a field command value that serves as a target for the field flux that is adjusted by the field adjusting mechanism, based on at least a rotation speed of the rotor, with a field limiting value, that is set according to the rotation speed of the rotor within a range in which induced voltage that is induced in the coil will not exceed a voltage resistance of the inverter, as an upper limit. |
