Abstract

A method for controlling an electromechanical actuator for a blinding device, including the associated electromechanical actuator and blinding device, comprises a step (E20) of electrically activating a motor. Following step (E20), the method includes a step (E30) of starting a motor shaft from zero rotational speed (V0) to reach a predetermined minimum rotational speed (Smin) during a starting phase (Pd). After reaching the minimum threshold value (Smin), the method includes a first step (E40) of controlling the motor shaft from the minimum threshold value (Smin) to a minimum rotational speed setpoint (Vmin).Following the attainment of the minimum rotational speed setpoint (Vmin) and the elapse of a predetermined time period (ΔtPd) of the start-up phase (Pd), the method includes a second step (E60) of controlling the motor shaft to a required operating rotational speed setpoint (Vn), starting from the minimum rotational speed setpoint (Vmin). See Figure 5 for the abbreviated version.
