Abstract
A magnetic gear embedded rotating electric machine control device, which controls voltage applied to a stator winding of a rotating electric machine having a magnetic gear therein so that an output from the rotating electric machine follows an output command, includes: a damping command generator which generates a damping command using an angle between a stator and a high-speed rotor of the rotating electric machine detected by an angle detector; a first adder which adds the damping command to the output command, to generate a corrected output command; and an output controller which controls an output generated by the rotating electric machine, in accordance with the corrected output command.
