A lithographic apparatus includes a movable part and a controller to control a position quantity of the movable part. The controller includes a first controller transfer function and a second controller transfer function. A selector selects the first controller transfer function or the second controller transfer function depending on a state of the movable part. The first controller transfer function may be chosen in a substantially stationary state of the movable part, while in a substantially non-stationary state of the movable part, the second controller transfer function may be chosen.
