  • Title: Model-based FDD Techniques for Real World Aerospace Vehicles
  • Abstract:
    Future aircraft design concepts are beginning to deviate from many of today’s common design conventions. One of the main issues for the development of future aircraft programs is to go further in sustainable and green transport, which is to provide society with an air transport that leaves a smaller carbon footprint. In this context, new technological options are more and more needed to produce incrementally more efficient and environmentally friendlier aircraft. Early and robust diagnosis of faults that may have an influence on structural loads contribute to the overall optimization of aircraft design, and so to weight saving for better overall performance in terms of fuel burn, noise, range and environmental footprint. The paper presents several case studies related to Fault Detection and Diagnosis (FDD) in aircraft electrical flight control system. The examples are taken from successful past and on-going collaborations and projects between Airbus Group and the University of Bordeaux (France) on model and signal based fault diagnosis in order to contribute to the above general goals. The presented techniques are nonlinear local filtering, black box modelling and parametric decision tests, and differentiation by higher order sliding modes. The examples are taken from past and on-going research projects and actions between Airbus Group and the University of Bordeaux (France). The techniques presented have been tested on highly representative aircraft benchmarks, real flight data, or through real-time implementation on Airbus test facilities and real A380 flight tests. The focus is on specific problems associated with each design when it comes to provide viable technological solutions and mechanization schemes. One of the model-based techniques which will be presented has received certification on new generation Airbus A350 aircraft and is flying (first commercial flight of A350 took place on the January 15, 2015).
