PROBLEM TO BE SOLVED: To provide a control device for a rotary electric machine capable of preventing compensation torque Tadd for cancelling vibration of a drive system from being made excessively large by a change in a change gear ratio of a change gear.SOLUTION: On the basis of a rotation speed detected by a motor rotation speed sensor, an MGECU 24 that defines a motor generator as a controlled system, extracts a vibration component Y that is included in the rotation speed and generated with the vibration of the drive system. On the basis of the extracted vibration component Y, the MGECU 24 calculates the compensation torque Tadd for cancelling the vibration of the drive system and on the basis of the calculated compensation torque, drive control of the motor generator is performed. Further, the MGECU 24 prevents the rotation speed that is used for extracting the vibration component Y, from being changed with the change in the change gear ratio of the change gear.SELECTED DRAWING: Figure 2 |
