Title:
MOTOR CONTROL DEVICE AND ELECTRO-MECHANICAL BRAKE DEVICE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2020/039720
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a motor control device which can estimate a delay with high accuracy and suppress an influence of the delay, even when there is a disturbance torque or a fluctuation in delay time. To this end, the present invention includes: a motor MTR; an ECU2 which controls the rotation of the motor MTR; and an ECU1 which transmits a torque command to the ECU2 on the basis of a command value. The ECU1 includes a disturbance estimation block 100 and a delay estimation block 200. The disturbance estimation block 100 estimates a torque command input to the ECU2 and a disturbance torque (τd) by using a feedback value from the motor MTR. The delay estimation block 200 estimates the delay by using the torque command output from the ECU1, the feedback value from the motor MTR, and the disturbance torque (τd).
