According to one embodiment, a position control apparatus includes: a digital control module that performs position control including disturbance adaptive control with a predetermined sampling period using a control constant, in accordance with a position error between a target position and a current position of the object; and a table that stores the control constant corresponding to a value of sin(ωT) or cos(ωT), wherein the digital control module is configured to determine a control value of the actuator in accordance with the position error, calculates the value of sin(ωT) or cos(ωT) according to an adaptive law from a signal based on the position error, reads the corresponding control constant from the table in accordance with the calculated value of sin(ωT) or cos(ωT), and updates the control constant, to perform the position control including the disturbance adaptive control.
