摘要:

针对采用Hammerstein模型描述电磁脉冲效应时模型参数确定困难的问题，提出一种基于优化Hammerstein模型的非线性电磁脉冲效应建模仿真方法。该方法利用高阶累积量求解模型线性延迟阶数，采用赤池信息准则（Akaike Information Criterion,AIC）优化模型非线性阶次，两者共同确定出一个参数最少、精度较高的最优模型，并以瞬态抑制器的电磁脉冲效应建模为例验证了该方法。

Abstract:

In order to solve the problem of model parameters determination when Hammerstein model is used to describe electromagnetic pulse(EMP) effect,the method of nonlinear EMP effect modeling and simulation based on optimized Hammerstein model is proposed.This method uses higher-order cumulant(HOC) to calculate the linear delay order of the model,and Akaike information criterion(AIC) norm is also used to optimize the nonlinear order of the model.Both results determine an optimal model with minimum parameters and high precision,and the EMP effect modeling for transient voltage suppressor(TVS) is taken as an example to verify the method.

Key words: electromagnetic pulse(EMP) effect transient voltage suppressor(TVS) Hammerstein model higher-order cumulant(HOC) Akaike information criterion(AIC)
