Abstract: A method for controlling a motorised drive device including an actuator coupled to a mechanical load includes steps of: a) detecting a loss of electrical power; b) subsequent to detecting a loss of power, transferring at least a portion of the energy stored in a first capacitor connected to the input of a voltage regulator of the drive device to a second capacitor connected to the output of the voltage regulator; c) determining, during a first time period following the loss of power, whether the load has moved; d) when power is restored, controlling the movement of the load into a predefined reference position if mechanical load movement has been determined, or otherwise maintaining the load in its current position.
