Abstract: A de-icing system which includes actuators attached to the part; and a device for controlling the actuators in order to vibrate the part. The control device is designed for the following, the actuators being divided into a plurality of groups: to control the actuators of a first one of the groups in order to establish a resonant frequency of the part; then to control the actuators of a second one of the groups in order to establish a resonant frequency of the part and, in parallel, to control the actuators of the first group in order to de-ice the part by vibrating it, using the resonant frequency established with this first group.

Abstract: An electrical control system intended for an aircraft turbojet engine nacelle includes two control modules of a single power module controlling an electric machine and an approval module linking each of the control modules to the single power module. The approval module selectively authorizes the control of the single power module by one of the control modules.
