Title:
MOTOR CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/059648
Kind Code:
A1
Abstract:
A motor control apparatus according to one embodiment of the present invention comprises: a current controller for generating a voltage command signal on the basis of a torque command for driving a motor and a fundamental wave current of the motor; a high frequency voltage generator for generating a high frequency voltage signal for injection into the voltage command signal; an inverter for applying a voltage to the motor on the basis of the voltage command signal and the high frequency voltage signal; an angle estimator for generating an estimated angle of a rotor of the motor on an estimated coordinate system on the basis of a current signal of the motor; and a compensator for adding a first compensation signal (icomp) to the current signal (isig), wherein the first compensation signal (icomp) may be related to the torque command and the estimated angle.
