摘要
本文给出估计非线性系统Wiener及Wiener-like模型参数的新方法。这种方法有以下几个方面:(1) 输入是多音频正弦信号;② 通过测量输出的稳态反应,得到系统的各阶Volterra核;(3) 根据频率域内各阶Volterra的相互关系可以分离出线性子系统的传递函数;④通过分离的线性传递函数,此类模型的参数估值可以简化为线性系统的参数估值问题。
In this paper, a novel method to estimate the parameters of nonlinear dynamic system Wiener and Wiener-like in frequency demain is presented. The method include the following stcps: 1) input signal is many tones sinusoid; 2) through measuring the steady state responses of the system, the Volterra kernels can be obtained; 3)by using the relations among Volte(?)ra kernels, the linear sub-system and nonliner components can be separate independently; 4) for separated linear sub-system, the parameters of estimations of nonlinear system can be simplified to the parameter estimations of linear system.
