ABSTRACT
Using neural networks, a method for the failure behavior
identification of a space antenna model is investigatd. Ieproposed
method employs three ssage& If a fault is suspected by the firt stage
of fault detction, a diagnostic test is performed on the antenna. The
diagnostic tests results are used by the second and third stages to
identify which fault occurred and to diagnose the extent of the fault,
respectively. The frst stage uses a multi-layer perceptron, the second
uses a multi-layer perceptron and neural networks trained with the
quadratic optimization algorithm, a novel training procedure, and the
third stage uses back-propagation tained neural networks.
