<P>PROBLEM TO BE SOLVED: To restrain a change (fluctuation) of a field coil current or stator coil current arising from rotation by drive control of a reluctance motor having a stator coil and a field coil, thereby obtaining a desired torque and output. <P>SOLUTION: A rotation angle detector 18 detects the rotation of a reluctance motor 2, and a current command value computing unit 20 outputs a torque command value for the reluctance motor 2 and a current command value for a stator coil current and field coil current. A main inverter unit 27 controls the stator coil current by voltage operation based on the current command value for the stator coil current, and a field inverter unit 30 controls the field coil current by voltage operation based on the current command value for the field coil current. A fluctuation correction unit 32a produces a correction value for reducing fluctuations in the field coil current arising from the rotation of the reluctance motor 2, so that the amount of voltage operation for the field coil current is corrected based on the correction value, thereby restraining a change (fluctuation) of the field coil current or stator coil current arising from the rotation of the reluctance motor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
