辨识Wiener模型的两步法

A Two-Stage Identification Technique for Wiener Model

本文利用稳态和动态信息提出了一种辨识Ｗｉｅｎｅｒ模型的新方法一两步法。该方法利用阶跃输入信号获取非线性增益的强一致性估计；利用不同幅值的周期脉冲输入信号获取线性子系统脉冲响应函数的强一致性估计。该方法具有辨识精度高和计算简单等优点，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 dynamics information to identifing wiener model is presented.The nonlinear gain and the impulse response functions of linear subsystem be obtained by using the step-changeds and cyclic impulse with dif- ferent amplitudes as input signals. The novel technique is simple and high identification accurate. Finally,the simulation results show that the new approach is very efficient and practical.
