| Abstract: | Aiming at the insufficiency of BP networks,such as the low learning convergence speed and instability learning performance caused by initial value,this paper proposed a new diagnosis method based on RBF neural net- works.The RBF networks structure and training algorithm applied to the condenser fault diagnosis was introduced. The typical learning,sample was established.Utilizing MATLAB neural network toolbox monitors and diagnoses the condenser status.Example verification indicated that RBF networks have very high learning convergence speed and better classified performance and RBF networks have good practicality in the field of fault diagnosis. |
