三层感知器算法的改进及其在故障诊断中的应用

Improved Algorithm for Three-Layer Perceptrons and Its Application to Fault Diagnosis

详细讨论了三层感知器算法的改进及其在汽轮机故障诊断中的应用 ,即对网络进行逐层优化 ,用这种方法训练三层感知器网络 ,网络收敛速度加快。在此基础上对某厂的汽轮机故障进行了诊断 ,结果表明 ,该方法能正确地诊断出存在的故障 ,具有一定的实用价值。

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.
