Workpiece transport control system and motion guidance device

A workpiece transport control system which transports a workpiece while movably supporting the workpiece using a motion guidance device having a track member which extends along a longitudinal direction and a moving member which is arranged so as to oppose the track member via a rolling element rollably arranged inside a rolling groove and which is relatively movable along the longitudinal direction of the track member, the workpiece transport control system comprising:

• one or a plurality of motion guidance devices;
• a transport table which is a table on which the workpiece is to be placed, the transport table being supported by the one or a plurality of motion guidance devices;
• an actuator which imparts a driving force so that the transport table is transported;
• a control unit which performs transport control by feedback control during transport of the workpiece by the actuator;
• and
• a calculation unit which calculates a transport load applied from the workpiece to the moving member of each of the one or a plurality of motion guidance devices, wherein
• the control unit adjusts a control gain related to the feedback control in the transport control on the basis of the transport load in each of the one or a plurality of motion guidance devices as calculated by the calculation unit.
