Abstract: The invention is directed to a method and an arrangement for controlling the position of an actuating element (1) which prevent damage to the actuating element by a collision with at least one stop (25, 30) and simultaneously ensure good dynamic characteristics. The position of the actuating element (1) tracks a desired value within a displacement range. The displacement range is limited for the actuating element (1) by at least one stop (25, 30). A check is made as to whether the distance between the desired value for the position of the actuating element (1) and the at least one stop (25, 30) drops below a pregiven value (S1). Only in this case is a change of the desired value limited.
