Title:
MOTOR CONTROL DEVICE, DRIVING DEVICE, AND POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/216050
Kind Code:
A1
Abstract:
A motor control device according to an aspect of the present invention is provided with: an inverter that drives a motor; and a control arithmetic unit that calculates a current command value indicating a current supplied from the inverter to the motor. The control arithmetic unit is provided with: a voltage control calculation unit that calculates, on the basis of current deviation between the current command value and the real current detected value, a voltage command value indicating a voltage applied from the inverter to the motor, and a compensation calculation unit that adds a compensation value to a signal value on at least one of the upstream side and the downstream side of flowing of a signal passed through the voltage control calculation unit. The voltage control calculation unit calculates the voltage command value through adaptive control based on a real angular speed value indicating an angular speed at which the motor rotates, and the compensation calculation unit calculates the compensation value on the basis of the real angular speed value and a target current command value.
