PROBLEM TO BE SOLVED: To provide a device for controlling a rotary electric machine capable of suppressing vibration appropriately.SOLUTION: A vibration component extraction part 41 of an MG (motor generator) control unit 30 extracts a vibration component of a frequency band including a vibration control target frequency f from the number of rotations N of the MG. A basic vibration control torque calculation part 42 calculates basic vibration control torque trq_vb on the basis of the extracted vibration component. A harmonic generator 43 generates a harmonic for correction which is a sine wave of a frequency n times as high as the vibration control target frequency f, n being an odd number of 3 or more. An amplitude adjustment part 44 and a phase adjustment part 45 calculate correction torque trq_c for correcting the basic vibration control torque trq_vb on the basis of the harmonic for correction. A vibration control torque calculation part 46 corrects the basic vibration control torque trq_vb on the basis of the correction torque trq_c, and calculates vibration control torque trq_v. A command correction part 49 corrects a torque command value trqon the basis of the vibration control torque trq_v. Thereby, the vibration of the vibration control frequency f is appropriately suppressed.SELECTED DRAWING: Figure 2
【課題】振動を適切に抑制可能な回転電機制御装置を提供する。【解決手段】MG(モータジェネレータ)制御部30の振動成分抽出部41は、MGの回転数Nから制振対象周波数fを含む周波数帯の振動成分を抽出する。基本制振トルク演算部42は、抽出された振動成分に基づき、基本制振トルクtrq_vbを演算する。高調波発生器43は、制振対象周波数fのn倍の周波数の正弦波である補正用高調波を発生する。nは、3以上の奇数である。振幅調整部44および位相調整部45は、補正用高調波に基づき、基本制振トルクtrq_vbを補正する補正トルクtrq_cを演算する。制振トルク演算部46は、補正トルクtrq_cに基づいて基本制振トルクtrq_vbを補正し、制振トルクtrq_vを演算する。指令補正部49は、制振トルクtrq_vに基づいてトルク指令値trq*を補正する。これにより、制振周波数fの振動を適切に抑制する。【選択図】図2
