Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2019/163587
Kind Code:
This motor control system is for driving a motor having a phase number n of 3 or higher. The system comprises an inverter and a control calculation unit for performing feedback control of the inverter. The control calculation unit comprises: a voltage control calculation unit for calculating, on the basis of current deviation between a current command value and an actual detected current value, a voltage command value indicating the voltage to be applied by the inverter to the motor; a torque ripple compensation calculation unit for adding a compensation value for compensating for torque ripples in the motor to an upstream and/or a downstream signal value in a stream of a signal passing through the voltage control calculation unit; and a current limit calculation unit for limiting the current command value via adaptive control using an actual angular velocity value indicating the angular velocity at which the motor is rotating.
