Title:
DRIVE-DEVICE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/043235
Kind Code:
A1
Abstract:
A technique that, without increasing the scale of a control device that controls a drive device provided with a variable-magnetic-flux dynamo-electric machine, can keep the induced voltage within the voltage tolerance of an inverter. This drive-device control device controls a drive device provided with: a dynamo-electric machine that has a rotor, provided with a permanent magnet, and a stator, provided with a coil; a magnetic-field adjustment mechanism that changes the magnetic flux supplied from the rotor; and an inverter connected to the coil. On the basis of at least the rotational velocity of the rotor, said control device determines a magnetic-field command value, which serves as a target value for the magnetic flux adjusted by the magnetic-field adjustment mechanism. Said magnetic-field command value is set to no more than a magnetic-field limit (Blmt
) set in accordance with the rotational velocity of the rotor such that the induced voltage induced in the coil does not exceed the voltage tolerance (Vmax
) of the inverter.
