辨识Hammerstein模型的两步法

A Two-Stage Identification Technique for Hammerstein Model

本文利用稳态和动态信息提出了一种辨识Ｈａｍｍｅｒｓｔｅｉｎ模型的新方法─—两步法．该方法利用稳态信息获取非线性增益的强一致性估计；利用动态信息获取线性子系统未知参数的强一致性估计．该方法具有计算简单和辨识精度高等优点．最后的仿真结果说明了该方法的有效性和实用性．

In this paper,a two-stage identification technique which uses both steady-state and dynamic information to identifying the nonlinear gain and linear subsystem of Hammerstein model,respectively,is prasented,and estimats obtained are strong consistenCy.The novel technique is simple and high identification accurate. Finally,the simulation results show that the new approach is very efficient and practical.
