Convex Models of Malfunction Diagnosis in High Performance Aircraft

Abstract

This project is devoted to the study of diagnosis of additive malfunctions in linear dynamic systems. This class of failures is relevant to control-actuator failures in aircraft, as well as to other situations. In particular, we are interested in optimizing multi-hypothesis maximum-likelihood algorithms for malfunction diagnosis, since this concept is the most widely accepted basis for automatic malfunction diagnosis. The engineering system to be studied is a linearized aerodynamic model for small disturbances about a reference condition of steady rectilinear flight over a flat earth. The advantage of this system is its simple description of a wide range of aerodynamic situations, and the fact that control-actuator malfunctions can be modelled as additive failures. Keywords: Computerized simulation; Modeling; Algorithms.
