| Abstract: | An improved algorthm for the three layer perceptrons and its application to the fault diagnosis of a turbogenerator are presented in the paper.The basic idea of the algorithm is to train the networks by use of layer by layer optimization technique to speed up the convergence of the networks.The result of a practical application of the algorithm to the fault diagnosis of a turbogenerator shows that an exact diagnosis of the fault can be made by the method. |
