Abstract

A control device controls a mechanical device having a movable member driven by a motor. The control device includes a radio signal exchange unit that receives a sensor signal indicating a position, a velocity or an acceleration of a tip part of the movable member, a data acquisition unit that acquires first time-series data of acceleration based on the received sensor signal, a data calculation unit that calculates second time-series data of acceleration at the tip part based on a drive command to the motor, a delay time calculation unit that calculates, when the mechanical device performs a predetermined basic operation, a delay time of the first time-series data to the second time-series data, based on a degree of correlation between the first and second time-series data, and a time synchronization unit that synchronizes time of the sensor part and control device based on the delay time.
