Abstract
A screen () includes a load bar (), a flexible element () supporting the load bar, and a controlled member () for winding the flexible member, wherein the member is controlled according to a method that includes controlling the angular movement of the winding member () with a temporal set value (θ(t)) of the instantaneous angular position of the winding member, the temporal set value being predetermined from a profile representative of the desired instantaneous axial position for the load bar upon a movement between the first and second positions, using a polynomial function of a degree higher than or equal to 2, which approximates the relation between a value of the instantaneous axial position (H(t)) of the load bar and an instantaneous angular position (γ(t)) of the winding member ().
