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.
