A control device is implemented that appropriately takes into account the influence of switching noise on the detected angle of a resolver. Said control device has: a correction information storage unit (25) that stores, as correction information (M) used to correct the detected angle (?), first correction information (M1) associated with the rotational velocity (?) of an AC motor (4), and second correction information (M2) associated with the modulation factor (R); a correction information acquisition unit (26) that acquires, in the case that the rotational velocity (?), at the time that the detected angle acquisition unit (27) acquires the detected angle (?) of the resolver (44), is equal to or greater than the rotational velocity threshold value (?0), the first correction information(M1) on the basis of this rotational velocity (?), and in the case that the rotational velocity (?) is less than the rotational velocity threshold value (?0), the second correction information (M2) on the basis of modulation factor (R) at the time of angle acquisition; and a detected angle correction unit (28) that corrects the detected angle (?) on the basis of the correction information (M). |
