Linear electromechanical actuators are popular in flight servo-actuation systems. Repertories of mandatory acceptance and health-monitoring tests result in the generation of large amounts of data. This poses challenges in handling the volumes of simi

In more electrical aircraft, most flight control wing surface actuators are either electro-hydrostatic or electro-mechanical, whether in manual or autopilot mode. Their reliability is essential for flight safety; failure of even one actuator can have

There have been some successful attempts to develop data-driven fault diagnostic methods in recent years. A common assumption in most studies is that the data of the source and target domains are obtained from the same sensor. Nevertheless, because e
