MOTOR CONTROL SYSTEM, CONTROL DEVICE, CONTROL METHOD, AND PROGRAM

Motor control system (10) includes position detection device (14), controller (12), and motor control device (16). Motor control device (16) includes a shift amount calculation unit that calculates a predicted arrival position of moving unit (50) based on positional information indicating a position of moving unit (50) detected by using position detection device (14) and distance information indicating a future moving distance of moving unit (50) based on an operation command, calculates a shift amount between the predicted arrival position and a target position of moving unit (50), and outputs information indicating the shift amount between the predicted arrival position and the target position. The shift amount calculation unit determines a reference point in time in consideration of at least one of an acquisition time required to acquire the positional information and an acquisition time required to acquire the distance information, acquires or calculates the position and the future moving distance of moving unit (50) at the reference point in time, and calculates the predicted arrival position based on the position and the future moving distance of moving unit (50) at the reference point in time.
