Abstract
A device for controlling a power-transfer system for the transfer of power between a high-pressure shaft and a low-pressure shaft of a turbomachine of an aircraft, including a fatigue analysis module analysing the fatigue of the turboma-chine and designed to determine, from between two indicators (D, D) respectively measuring two fatigues of the turbomachine, which is the one that is the most advanced, which is to say which is the one at risk of being first to reach a respective upper limit (Dmax, Dmax); and—a control module controlling the power transfer system and designed to slow the fatigue measured by the more advanced indicator (D, D).
