MOTOR CONTROL APPARATUS AND MOTOR CONTROL METHOD

摘要

A motor control apparatus includes a state quantity detector configured to output a detection signal in correspondence with a state quantity of a motor, a vibration detection unit configured to detect a disturbance vibration component of the motor based on a torque instruction and the detection signal and output a vibrational component signal in correspondence with the detection result, a speed signal generator configured to generate a speed signal based on a result of subtracting the vibration component signal from the detection signal, and a speed controller configured to generate the torque instruction based on a deviation between a speed instruction and the speed signal.
