Title:
CONTROL DEVICE OF ROTATING ELECTRIC MACHINE AND METHOD FOR CONTROLLING THE SAME
Document Type and Number:
WIPO Patent Application WO/2014/188264
Kind Code:
A3
Abstract:
An electronic control unit includes calculating a slip frequency of a rotating electric machine from a torque instruction value to the rotating electric machine and a target value of output efficiency to the rotating electric machine, calculating a frequency of the instruction signal from the slip frequency and a rotational frequency of the rotating electric machine, the slip frequency being changed by changing the target value of the output efficiency with the torque instruction value maintained and changing the slip frequency so as to change the frequency of the instruction signal to out of an inverter lock frequency band when the frequency of the instruction signal is included in the inverter lock frequency band.
