Abstract

A method for controlling a part movable with a coil. In this case, a current flowing through the coil and/or a voltage applied to the coil is/are scanned in order to generate a coil signal. In a further step, at least one movement parameter representing an oscillatory movement of the part is ascertained by using the coil signal. Finally, at least one signal parameter of a dither signal is optionally changed to generate the oscillatory movement by comparing the movement parameter to the at least one setpoint value to adapt the oscillatory movement to the setpoint value.
