PROBLEM TO BE SOLVED: To provide a rotating electrical machine control unit capable of preventing the excessive increase of compensation torque Tadd for cancelling the vibration of a driving system.SOLUTION: A MGECU 24 for controlling a motor-generator extracts a vibration component Y that is contained in a rotating speed detected by a motor rotating speed sensor and that is generated as a driving system vibrates on the basis of the history of the rotating speed. Furthermore, the MGECU 24 calculates compensation torque Tadd for cancelling the vibration of the driving system on the basis of the extracted vibration component Y, and implements a driving control over the motor generator on the basis of the calculated compensation torque. Moreover, the MGECU 24 performs shift variation removal processing for suppressing the rotating speed for use to extract the vibration component Y from changing depending on a change of a transmission gear ratio of a transmission. Furthermore, the MGECU 24 performs processing for suppressing a sudden change in the vibration component Y, for example, before and after the switchover from determination to prohibit the execution of the shift variation removal processing to determination to permit the execution.SELECTED DRAWING: Figure 2
【課題】駆動系の振動を打ち消すための補償トルクTaddが過度に大きくなることを回避できる回転電機の制御装置を提供する。【解決手段】モータジェネレータを制御対象とするMGECU24は、モータ回転速度センサによって検出された回転速度の履歴に基づいて、上記回転速度に含まれる振動成分Yであって、駆動系の振動に伴い生じる振動成分Yを抽出する。また、MGECU24は、抽出された振動成分Yに基づいて、駆動系の振動を打ち消すための補償トルクTaddを算出し、算出した補償トルクに基づいて、モータジェネレータの駆動制御を行う。さらに、MGECU24は、振動成分Yの抽出に用いられる回転速度が変速装置の変速比の変更に伴って変化することを抑制する変速変化量除去処理を行う。加えて、MGECU24は、変速変化量除去処理の実行の禁止判定から許可判定への切り替え前後等において、振動成分Yの急変を抑制する処理を行う。【選択図】 図2
