  • Patent number: 10626669
    Abstract: The present invention relates to a method of controlling an actuator for a mobile item of equipment in building comprising the steps consisting in: deploying a model (M) linking at least one modelling parameter (P) with at least one characteristic physical quantity (C) of the environment or of the operation of the actuator exhibiting a temporal evolution; collecting a set of measurement values (VCm) relating to the at least one characteristic physical quantity (C) of the environment or of the operation of the actuator in the course of a measurement interval (Tm), each measurement value (VCm) being associated with an instant (Tm) of the measurement interval (Tm); determining or correcting at least one value (VP) of the at least one modelling parameter (P) in such a way that a modelled temporal evolution (Ee) defined on the basis of the application of the model (M) of the at least one value (VP) of modelling parameter (P) corresponds to or approaches an observed temporal evolution (Eo) of the characteristic phy

  • Patent number: 9599996
    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 (?(t)) of the instantaneous angular position (?(t)) of the winding member (52).

  • Patent number: 9564792
    Abstract: The invention relates to an electric motor having a rotor and a coiled stator, the rotor including a shaft and two disks that are rotatably fixed to the shaft and provided with permanent magnets, an outer portion of the stator extending from each disk axially parallel to a rotational axis of the rotor and radially beyond same, from the axis. The stator includes a plurality of disjointed bars made of a magnetically conductive material, certain parts of which form the outer portion of the stator. The stator also has a carrier structure holding the bars such that they are fixed in relation to each other, the carrier structure being mounted in such a way that it can rotate on the shaft, axially outside the two disks. The outer portion of the stator extends parallel to the rotational axis, axially outside the disks of the rotor, up to the carrier structure.

  • Patent number: 9080382
    Abstract: A screen (1) includes a load bar (2), a flexible element (3) supporting the load bar, and a controlled member (4) for winding the flexible member, wherein the member is controlled according to a method that includes controlling the angular movement of the winding member (4) with a temporal set value (?(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 (?(t)) of the winding member (4).

  • Patent number: 8853973
    Abstract: Each screen (1) of a group of screens is configured by a method in which a function is approximated, the function giving the instantaneous axial position (H(t)) of the load bar (2) thereof along an axis (Z) of translation in the form of a function having, as a variable, the instantaneous angular position (y(t)) of a winding device (4). The load bars of the screens are sequentially moved into a plurality of positions in which the load bars are aligned, and then the angular position (y(t)) of the winding device is determined. Next, the coefficients defining the approximation function of each screen are determined. The movement of the load bar of each screen is controlled by an instantaneous angular-position set value (?(t)), which is in turn predetermined from a representative profile using the one-to-one approximation function.
