    摘要: Provided is a synchronization control device that can control a mechanical system with good track followability. A control unit for each shaft of the synchronization control device includes: a delay time compensator which delays a position command to an FB torque command generation unit, and of which equivalent time constant is approximately the same as an equivalent time constant as a gain compensator. The synchronization control device also includes a phase adjustment unit, which adjusts a phase of at least one of the position commands, in a previous stage of each control unit, so that the time until the position command, input to each control unit, is output from the delay time compensator, becomes approximately the same.
