Synchronization control device, synchronization control system, synchronization control method, and simulation device

A synchronization control method comprising:

• a main axis command calculation step of calculating a main axis command position with respect to a main axis servo control mechanism based on time-series target position information with respect to the main axis servo control mechanism;
• a main axis model calculating step of calculating a predicted main axis feedback position of the main axis servo control mechanism by a dynamic characteristic model of the main axis servo control mechanism by inputting the main axis command position, a main axis feedback position of the main axis servo control mechanism, and a predicted main axis command position after a predetermined time calculated based on the target position information;
• and
• a driven axis command calculation step of calculating a driven axis command position with respect to a driven axis servo control mechanism based on a predicted main axis feedback position of the main axis servo control mechanism calculated by the main axis model calculating step.
