Abstract
A servo control device including a servo control unit that calculates a drive command that causes a feedback position from a motor to be driven to follow a command position, to drive the motor according to the drive command, a moving-state determination unit that determines a speed of the motor is by simulating a response of the motor, and outputs a determination result as a moving state, a correction-amount selection unit that selects a correction amount according to a change pattern of the moving state at a timing when the determined moving state changes, and an addition unit that adds the correction amount output from the correction-amount selection unit to the drive command calculated by the servo control unit to generate a corrected drive command, and sets the corrected drive command as a drive command to the motor instead of the drive command calculated by the servo control unit.
