Title:
MOTOR CONTROL DEVICE FOR ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP2015204649
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent the generation of vibration or noise in a driving system caused by response delay of current control or torque ripple under such high revolution that a response amplitude in a high frequency of the current control is changed.SOLUTION: A motor control device includes torque ripple calculation means 5 including torque ripple amplitude maps 10 and 20, torque ripple phase maps 11 and 21 and torque ripple calculation parts 16 and 22. The torque ripple calculation means 5 also includes a plurality of kinds of torque ripple compensation means including a same-order torque ripple calculation part for calculating the torque ripple of the same order; and output magnification setting parts 17 and 23 for adding output magnifications of torque ripple calculated and outputted by the same-order torque ripple calculation part after changing them in accordance with a rotation speed of a motor 2.
