MOTOR CONTROL SYSTEM, AND POWER STEERING SYSTEM

WIPO Patent Application WO/2019/163553

A1

One mode of a motor control system comprises an inverter that drives a motor, and a control calculation unit that calculates a current command value showing the current supplied to the motor from the inverter. The control calculation unit comprises: a voltage control calculation unit that, on the basis of the current deviation between the current command value and the actual current detection value, calculates a voltage command value indicating the voltage applied to the motor from the inverter; and a compensation calculation unit that compensates for a k-order component and/or 1/k-order component in the motor with respect to a signal value in the upstream side and/or downstream side in the flow of signals passing through the voltage control calculation unit. The compensation calculation unit calculates a compensation value on the basis of an actual angular velocity value showing the angular velocity at which the motor rotates and the target current command value, and in consideration of advance-angle control.
