Modern aircraft must be equipped with suitable monitoring devices to avoid malfunctioning of the PFC, such as control surface oscillations. Methods of model-based fault diagnosis are proposed to reduce the level of failure-case-induced structural loads. Validation is accomplished by means of an experimental test rig and an aeroservoelastic aircraft model.
