Title:
ROTATING MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/054232
Kind Code:
A1
Abstract:
Provided is a rotating machine control device that is capable of accurately reducing ripple components by correcting the output torque of the rotating machine, even when the phase of a ripple component relative to the angle of rotation changes in accordance with the rotational speed. A rotating machine control device (30) periodically changes a torque correction value (ΔToc) in accordance with the angle of rotation (θ) and changes the torque correction value phase (α) relative to the angle of rotation (θ) on the basis of the rotation speed (N), and applies a voltage to multi-phase windings on the basis of a post-correction torque command value (Toc) in which a torque command value (To) was corrected using the torque correction value (ΔToc).
