Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/172207
Kind Code:
A1
Abstract:
[Problem] To provide a motor control device which makes it possible to execute a torque ripple-suppressing control which is highly followable by executing a direct voltage control. [Solution] A motor control device equipped with: a voltage command calculation unit 15 which calculates a d-axis voltage command value Vd
ref and a q-axis voltage command value Vq
ref on the basis of a d-axis current command value id
* of a motor 6 and a q-axis current command value iq
* thereof; a feed forward command value calculation unit 23 for calculating a q-axis voltage feed forward command value Vqff
* for generating a q-axis current ripple on the basis of space harmonic parameters and motor winding frequency properties; and a subtraction unit 10 which subtracts the q-axis voltage feed forward command value Vqff
* calculated by the feed forward command value calculation unit 23 from the q-axis voltage command value Vq
ref calculated by the voltage command calculation unit 15.
