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.
