Abstract
To suitably set a control gain in feedback control while suppressing an increase in apparatus size. A workpiece transport control system includes: one or a plurality of motion guidance devices; a table on which a workpiece is to be placed; an actuator which imparts a driving force to the table; a control unit which performs transport control by feedback control; and a calculation unit which calculates a transport load applied from the workpiece to a moving member of each of the one or a plurality of motion guidance devices, wherein a control gain related to the feedback control in the transport control is adjusted on the basis of the transport load in each of the one or a plurality of motion guidance devices.
