It is constructed so as to be able to follow without delay and flexibly cope with a change in a command of a host controller in the case of receiving a target command value at the present time from the host controller every certain period. In a servo control apparatus 2 for causing an output of a controlled object 3 to follow target commands received from a host controller 1 every certain period, predictive target commands to the next M steps are generated every each period using a history of the target commands and command follow-up control is performed by predictive and preview control or feedback gain switching control using the predictive target commands.
