Abstract
The invention relates to a method for positioning an actuator. In the method, the actuator is controlled by a continuous control pulse (,) toward a desired value (,), and the position of the actuator is measured. Further, a pulsing range limit located before the desired value (,) is defined, and when the position of the actuator is past the pulsing range limit (,), the motion of the actuator is stopped. The pulsing range limit (,) is defined to be so far from the desired value (,) that the actuator stops before its position is substantially past the desired value (,). The position of the actuator is then measured, and if necessary, a corrective run is performed.
