  • Method and device for detecting oscillatory failures in a position servocontrol subsystem of an aircraft control surface
    Patent number: 9216830
    Abstract: Methods and devices for detecting oscillatory faults in a positional servocontrol arrangement for an aircraft control surface are provided. The detection device estimates a reference position of the control surface and, with the aid of a model in which at each iteration a residual value of the previous iteration, multiplied by a dynamic gain, is injected, detects an oscillatory fault with the aid of this reference position.
