Abstract
A motor control device includes a movement command generator that outputs a movement command of a motor, a filter that performs filter processing of the movement command and outputs the filtered movement command, and a position controller that performs a position control of the motor. The filter is an infinite impulse response digital filter that is represented by a transfer function H(z): H(z)=(b0+b1·z+b2·z)/{1−(a1·z+a2·z)} with filter coefficients a1, a2, b0, b1, and b2. The filter is configured to change the filter coefficient b0 in a first sample period, to change the filter coefficients a1 and b1 in a second sample period which follows the first sample period, and to change the filter coefficients a2 and b2 in a third sample period which follows the second sample period.
