MOTOR CONTROL DEVICE, MOTOR CONTROL METHOD, AND MOTOR CONTROL PROGRAM

WIPO Patent Application WO/2022/202331

A1

Provided are a motor control device, a motor control method, and a motor control program that can control the rest position of a motor with high precision.　The present invention comprises: a drive signal generation unit; a target voltage value generation unit that generates a target voltage value on the basis of a drive signal; a comparator that outputs the results of comparison of the target voltage value and a voltage value corresponding to a drive current applied to a stepping motor; and a control signal generation unit that generates a control signal that controls the drive current. The drive signal generation unit comprises: a first adjustment unit that adjusts the drive signal so that, over a longer time than the time it would take the stepping motor to reach a target drive position if the drive current were switched from an initial value to a target drive current value instantaneously, the drive current will change from the initial value to the target drive current value; and a second adjustment unit that adjusts the drive signal so that the drive current, after overshooting a maximum current value that is greater than the target drive current value for a prescribed time, will return to the target drive current value.
