Title:
CONTROL DEVICE, MECHANICAL SYSTEM AND TIME SYNCHRONIZATION METHOD
Document Type and Number:
Japanese Patent JP2020192628
Kind Code:
A
Abstract:
To easily synchronize time of a control device with time of a wireless sensor in suppressing vibration by learning control.SOLUTION: A control device, which controls a mechanical device having a movable member that is driven by a motor, comprises: a wireless signal transmitting/receiving part that receives a sensor signal representing a position, a speed or an acceleration of a tip part detected by a sensor part at the tip part of the movable member of the mechanical device; a data acquiring part that acquires first time-series data on the acceleration on the basis of the received sensor signal; a data calculating part that calculates second time-series data on acceleration of the tip part of the movable member from a driving command from the motor; a delay time calculating part that calculates delay time of the first time-series data relative to the second time-series data, in accordance with a degree of correlation between the first time-series data and the second time-series data, when operating the mechanical device by predetermined basic operation; and a time synchronization part that synchronizes time of the sensor part with time of the control device on the basis of the delay time.SELECTED DRAWING: Figure 2
