Abstract
A motor control device of the present invention includes: target electric current value setting units (and) that set target electric current values that should be supplied to a motor (), basic voltage value computing units (, and) that compute basic voltage values for driving the motor, a rotation angle speed computing unit () that computes a rotation angle speed of the motor, correction value computing units (, and) that compute correction values for correcting the basic voltage values based on motor electric current values and a rotation angle speed of the motor, correcting units (and) that obtain voltage command values by correcting the basic voltage values by the correction values computed by the correction value computing units, and a driving unit () that drives the motor by using voltage command values. The correction value computing units include correction value smoothing units (, and) for obtaining smoothed correction values.
