Title:
ROTATING ELECTRICAL MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/228404
Kind Code:
A1
Abstract:
This rotating electrical machine control device is provided with a rotating electrical machine, a power converter, a current detection unit, a rotation sensor, a rotation arithmetic operation unit, a d-axis current command value generation unit, a q-axis current command value generation unit, a voltage command value calculation unit, and a switching control unit. This rotating electrical machine has a d-axis inductance Ld that is greater than a q-axis inductance Lq. The rotation arithmetic operation unit reduces the angle error resulting from a rotation sensor detection error, on the basis of at least one of the rotation sensor output signal, a current, and a voltage command.
