To provide a servo control device following without delay from a host instruction by improving the following accuracy without involving overshoot or continuation vibration.
An instruction signal is directly transmitted to a controller 20 as target instruction increment value. A compensation signal computing unit 10 inputs the target instruction increment value, and transmits a compensation signal generated by subtracting the target instruction increment value from a signal passed to an inverse transfer transmission function device having inverse transfer function characteristics of an optional low pass filter followed by multiplying by an adjustment gain to a control object 1. The controller 20 inputs the target instruction increment value and an output increment value of the control object 1 and transmits a control input to the control object 1 so that a target instruction is matched with the output of the control object 1.
