A non-stationary signal correlator for on-line transit time estimation.
T. Tambouratzis and M. Antonopoulos-Domis
TThe on-line reliable estimation and monitoring of transit time
in BWRs is investigated. The interactive activation-competition artificial
neural network is employed for providing an estimate of the current transit
time directly at each incoming pair of signal values. As a result, transit
time monitoring is accomplished for both constant and oscillating flow regimes,
i.e. for both stationary and non-stationary signals. The proposed approach
is robust to the presence of local and global component as well as to the
addition of white uncorrelated noise.
