Title:
MOTOR CONTROL DEVICE, ELECTRIC ACTUATOR PRODUCT, AND ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/053167
Kind Code:
A1
Abstract:
This motor control device comprises: a current command value calculation unit (41) that calculates a current command value for driving a motor; a current value detection unit (48) that detects current flowing in the motor; a current control unit (52) that outputs a first voltage command value in accordance with the deviation between a current detection value, which is the detection value of the current detected by the current value detection unit (48), and the current command value; a voltage disturbance suppression unit (53) that calculates a second voltage command value by adding the output of a delay element (55) to the first voltage command value, and that inputs the second voltage command value into the delay element (55); and a driving circuit (47) for driving the motor on the basis of the second voltage command value.
