Abstract:

　 BP algorithm trends to fall into the local minimum value , slow convergence speed and frequent oscillation.The wave let BP network was used , and self -adaptive learning rate algorithm based on the sign change of gradient and momentum item we re added in it .The improved algorithm was applied in Tennessee -eastman process of a multiple - variable and nonlinear system .The results show that the algorithm can improve the recognition accuracy of fault classification.

Key words: Wavelet network, , Fault diagnosis, , Tennessee - eastman process

摘要： 　针对BP 算法容易陷入局部极小值、收敛速度慢及容易振荡等缺点, 采用小波BP 网络且对小波网络采用基于梯度符号变化的局部学习率自适应算法和引入动量项的改进。将改进后的算法对多变量非线性的田纳西-伊斯曼过程进行了仿真研究, 结果表明改进算法提高了故障分类的辨识精度。
