Abstract
A servo control device controls a combined position of a first servo system and a second servo system having higher response than response of the first servo system. The servo control device includes a first axis target value creation unit and a correction unit. The first axis target value creation unit creates a first axis target value based on a combined command value which is a position command value of the combined position. The correction unit converts the first axis target value into a first axis command value by using a first transfer function. In addition, the correction unit converts the first axis target value by using a second transfer function, and calculates a second axis command value by subtracting the converted first axis target value from the combined command value. The product of the first transfer function and a first model transfer function which models characteristics of the first servo system is equal to the product of the second transfer function and a second model transfer function which models characteristics of the second servo system.
