<P>PROBLEM TO BE SOLVED: To provide a control device for a rotary electric machine capable of suppressing shaft torsional vibration produced in the power transmission system of a vehicle, without canceling disturbance torque such as running resistance torque or brake torque. <P>SOLUTION: The control device for the rotary electric machine includes: an external input estimator 41 that reduces the vibration component of the power transmission system and estimates transmission system input torque Tin on the basis of rotational speed ωm of the rotary electric machine, and that estimates external input torque Tw by subtracting output torque Tm of the rotary electric machine; a low-vibration speed calculator 42 that calculates a low-vibration rotational speed ωm^ on the basis of the external input torque Tw and vehicle request torque Tr; a rotational speed controller 43 that calculates a feed back command torque Tp which makes the rotational speed ωm of the rotary electric machine be matched with the low-vibration rotational speed ωm^; and a torque command value calculator 44 that calculates an output command value Tmo. <P>COPYRIGHT: (C)2012,JPO&INPIT |
