<p>The method involves identifying a crossing of a median position by a position set point of a shutter, and identifying the approaching of the median position by the shutter. A determined quantity is added to an electric current parameter, which is provided to a driving motor, during a predetermined duration when the median position is attained by the shutter. An inverse crossing of the median position is controlled by the position set point during the determined duration.</p> |
