Abstract:
A motor control apparatus includes a power converter, a speed controller, and a stop position controller. The power converter outputs a current to drive a motor based on a torque command. The speed controller generates the torque command based on an error between a speed command of the motor and a speed of the motor. The stop position controller calculates an acceleration command to output a predetermined torque after detection of a reference position per revolution of a position detector for a first time during speed control of the motor, generates a torque feed-forward command based on the acceleration command, generates a position command based on the acceleration command, and generates the speed command based on an error between the position command and the motor position to execute position control of the motor.
