Research on diagnosis of faults for nuclear marine apparatus based on probability neural net
Ning Zhang · China Shiprepair · 2009
Nuclear marine apparatus is a huge complicated system,most of which equipments are of nonlinearity,time varying,coupling and inexactness.Neural net is widely applied in nuclear fault diagnosis for its approaching any kinds of nonlinearity mapping.At present,BP neural net is used more widely,but the layers of the net and the neurones on each layer can not be delimited easily;such net may fall into the minimum point in the course of training.In this essay,PNN proves effective in diagnosing faults on nuclear marine apparatus.
