US Patent 7759893 Motor control apparatus and motor control method

The motor control apparatus includes a memory that stores a correction data group for suppressing a fluctuation of an output of a motor, and a calculating unit that generates, by using a correction value calculated on the basis of a first output command value input thereto and the correction data group, a second output command value for controlling the output of the motor, the correction value being in accordance with operation position information of the motor. The memory stores plural correction data groups corresponding to predetermined output command values for different torque levels. The calculating unit calculates the correction value in accordance with the first output command value and the operation position information of the motor by interpolation processing using correction data included in at least two correction data groups among the plural correction data groups. The apparatus suppresses the output fluctuation of the motor.
