Automated Failure Effect Analysis for PHM of UAV

Reference work entry

Abstract

This chapter describes how model-based simulation can be employed to automatically generate the system-level effects for comprehensive sets of component failures on systems within the aircraft. The results of the simulation can be used in several ways. They can be used to produce a system-level failure modes and effects analysis (FMEA) for aircraft systems. They can be used to identify the sensors necessary to discriminate remotely between different failures on the aircraft. Once a set of sensors have been chosen for placement on the vehicle, the simulation results can also be used to generate diagnostic and prognostic software for deployment on the vehicle.

Using automated FMEA safety analysis software is more efficient than doing the same work without software and also provides a guaranteed level of performance. Using the results of this analysis can provide sensor selection and diagnostic capability while retaining some of the benefits of rule-based diagnostic systems. Alternative model-based techniques have been widely used to create diagnostic systems in a variety of domains, and these approaches are compared with the diagnostic capability provided by a failure effect-oriented technique from the perspective of the UAV application.
