A position control apparatus includes a detecting unit (1) configured to detect a position of a control target, a subtracting unit (2) configured to subtract an output of the detecting unit from a target value, an iterative learning control circuit (6) including a filter into which a deviation between the output of the detecting unit (1) and the target value is input, where the iterative learning control circuit (6) feeds forward a control input to the control target, and a parameter computing unit (Z) configured to compute a variation in a parameter of the control target. A characteristic of the filter is computed in accordance with the variation in the parameter of the control target.
