    Abstract

    The report describes model based techniques of failure detection, isolation and estimation for aircraft control surfaces and actuators. An extensive survey of the existing13; techniques are presented. For surface damage detection and isolation two different techniques have been suggested. Both these techniques use fault detection filters and are based on percentage gain surface loss failure model. Innovation based techniques are used to detect faults13; in the actuator. All the proposed techniques have been evaluated using a full six-degrees of freedom simulation model of DLR in-flight simulator ATTAS. For this purpose the six-degrees of freedom simulation model has been implemented using Simulink-Matlab.
