非线性系统Hammerstein模型辨识

Identification of the Nonlinear System's Hammerstein Models

本文利用差集理论设计的输入信号。辨识了Hammerstein模型的脉冲响应函数,并进一步得到了非线性部分多项式的系数。本文得到的公式简单,辨识结果依概率收敛于真值。文中给出了仿真结果。

The paper uses the input signals designed by the difference sets theory to identify the impulse response functions of the nonlinear system's Hammerstein model. The polynomial coefficients of the nonlinear subsystem have been further obtained. The obtained formulas are very simple,and the probability of identification results are consistently convergent to their original ones. Some simulation results are also given in it.
