This paper describes a study related to the testing and validation of
a neural-network based approach for the problem of actuator failure de
tection and identification following battle damage to an aircraft cont
rol surface. Online learning neural architectures, trained with the Ex
tended Back-Propagation algorithm, have been tested under nonlinear co
nditions in the presence of sensor noise. In addition, a parametric st
udy has been conducted that addresses the selection of 'near optimal'
neural architectures for online state estimation purposes. The Failure
Detectability/False Alarm Rate ratio problem has also been considered
in this study. The testing of the approach is illustrated through typ
ical highly nonlinear dynamic simulations of a high performance aircra
ft.
