Abstract
A method to be used for controlling a screen (1) including a load bar (2), a flexible element (4) supporting the load bar, and at least one controlled member for winding the flexible member, in order to move the load bar (2) between a first high or low position and a second low or high position, the movement resulting from an angular movement of the winding member. The method includes at least one step in which the angular movement of the of the winding member (52) is controlled with a temporal set value (θ(t)) of the instantaneous angular position (γ(t)) of the winding member (52).
