PROBLEM TO BE SOLVED: To provide a rotary electric machine control device that hinders a sudden change of output torque of a rotary electric machine.SOLUTION: A rotary electric machine control device for controlling drive of an MG 80 comprises: a rotation angle detecting section 51 that is able to detect a rotation angle of the MG 80; a collection correction value calculating section 54; a correction value adding section 55, and an electric current control section. The collection correction value calculating section 54 calculates a correction value Vc for correcting a rotation angle detection value θd, on the basis of a simultaneous error Δθ calculated by the error calculating section 52 and a deviation error AveΔθ calculated by a deviation error calculating section 53. The correction value adding section 55 calculates separate correction values obtained by dividing an amount of change in correction value into at least two or more, which are smaller than the absolute value of a predetermined value when the absolute value of the amount of change in correction value, i.e., a difference between the correction value Vc immediately before and the current correction value Vc, is equal to or higher than the absolute value of the predetermined value. The correction value adding section then simultaneously calculate a post-correction rotation angle θvc in which the separate correction values are added to the rotation angle detection value θd. The electric current control section controls drive of the MG 80 on the basis of the post-correction rotation angle θvc.SELECTED DRAWING: Figure 1

    【課題】 回転電機の出力トルクの急変を抑制する回転電機制御装置を提供する。【解決手段】 MG80の駆動を制御する回転電機制御装置は、MG80の回転角を検出可能な回転角検出部51、まとめ補正値算出部54、補正値加算部55、および、電流制御部を備える。まとめ補正値算出部54は、誤差算出部52が算出する逐次誤差Δθおよび偏り誤差算出部53が算出する偏り誤差AveΔθに基づいて回転角検出値θdを補正する補正値Vcを算出する。補正値加算部55は、直前の補正値Vcと今回の補正値Vcとの差である補正値変化量の絶対値が所定値の絶対値以上のとき補正値変化量を所定値の絶対値に比べ小さい少なくとも二つ以上に分割した分割補正値を算出し、当該分割補正値を回転角検出値θdに加算した補正後回転角θvcを逐次算出する。電流制御部は、補正後回転角θvcに基づいてMG80の駆動を制御する。【選択図】 図1
