Abstract: A method for operationally controlling a motor-driven device for driving a home automated closure or sun-shading apparatus includes at least the following steps: —measuring (E21), via a measuring device, a first value of the strength of an electrical current passing through an electric motor; —determining (E24) a difference in strength relative to the first measured strength value after a period of time starting from the moment that the first strength value is measured has elapsed; —selecting (E25) one of the first threshold strength values on the basis of the elapsed time period; —comparing (E26) the difference in strength determined relative to the selected threshold strength value; and —determining (E27) the presence or absence of an obstacle or end of travel on the basis of the result of the comparison step (E26).

Abstract: The invention relates to a method for generating control signals for managing the operation of a synchronous motor with one or more permanent magnets (1) comprising a stator (2), the stator comprising a number P of phases (3, 4, 5), a rotor, the rotor comprising said permanent magnet or magnets, a switching module (6) provided with a plurality of switches (K1-K6), a number N of Hall-effect sensors sensitive to a rotating electromagnetic field induced by said permanent magnet or magnets, N being no lower than 2 and strictly lower than P, the method comprising a step of acquiring status information transmitted by the sensors (9, 10) and a step of estimating at least one piece of complementary information on the basis of status information transmitted by the sensors (9, 10), the complementary information characterising the status variation of at least one virtual sensor. The invention also relates to a control device (10) comprising a module for estimating a piece of complementary information (11) and a module for generating control signals (12) configured to implement the method. The invention further relates to an actuator (9) comprising a synchronous motor with permanent magnets (1) and a control device (10).

Abstract: The disclosed method enables control of an actuator for winding a blackout screen around a winding shaft. The actuator includes at least one electric motor. The method includes: at least one step that involves using an electronic unit to detect screen locking, during lowering or raising, by detecting a torque exerted by the motor on the winding shaft, the torque being determined on the basis of a current for supplying power to the motor; and a step that involves stopping the motor when a signal representing the detected current is greater than a threshold value. The electronic unit is parametrizable. Moreover, the method includes at least one additional step, used when the signal representing the detected current is less than the threshold value and involving detecting, on the basis of the detected current, a localized change in the shape of the screen, during lowering, by using the same electronic unit.

Abstract: A method for controlling and/or protecting an actuator of a piece of mobile equipment of a building, the actuator comprising a motor, comprises the steps consisting of: (E1) providing an instantaneous signal representative of the electrical power provided to the motor, (E2) carrying out a sampling of values of the instantaneous signal, (E3) performing a control of each sampled value according to a first protection criterion of the actuator, and issuing a first piece of anomaly information for each sampled value that does not satisfy the first criterion, (E3′) acquiring a set of values from the sampled values, (E4′) performing a control according to a second protection criterion of the actuator applied to all of the acquired sampled values, and issuing a second piece of anomaly information for all of the acquired sampled values that do not satisfy the second protection criterion.
