Title:
ELECTRIC MOTOR CONTROL DEVICE AND ELECTRIC BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/012799
Kind Code:
A1
Abstract:
Provided is a novel electric motor control device with which control responsiveness is enhanced and the occurrence of an overshoot can be suppressed. The electric motor control device is provided with: a state feedback control block (51) for feeding back a state quantity of an electric motor (MTR) to a control command value; a disturbance estimation block (52) for estimating a disturbance of the electric motor (MTR); and a disturbance suppression block (53) for generating a disturbance suppression signal on the basis of the output of the disturbance estimation block (52). When a disturbance occurs, the disturbance suppression signal (Ds) is reflected in the control command value (τ*) so that the control quantity of the electric motor (MTR) matches the control command value. In this way, control responsiveness is enhanced and the occurrence of an overshoot can be suppressed.
