非线性动态网络的通用分析方法与故障诊断

A Universal Method of Analysis And Research on Fault Diagnosis for Nonlinear Dynamic Networks

基于规范式分段线性化总体表达式并应用网络的一些基本知识,列出了非线性动态网络规范式分段线性化方程组.用该法分析动态网络无需计算响应跨越边界的时间,并能将整个动态过程的计算转化为代数的递推运算.在动态网络响应易于用计算机仿真的基础上,提出了基于小波-神经网络的非线性动态网络故障诊断的基本思想.

By using method of canonical piece-wise linearization and fundamental knowledge of circuit theory,a set of canonical piece-wise-linear equations for nonlinear dynamic networks is presented.This analysis method needn't calculate the time when the response crosses a boundary.The another advantage of this method is that the calculation of dynamic response is converted to algebraic recursive computation.Because the dynamic response can easily be resolved by computer simulation,a basic idea of fault diagnosis method of nonlinear dynamic networks based on wavelet-neural network is also briefly decribed.
