| 中文摘要 |
| 本文提出一种辨识连续Hammerstein模型参数的方法。该方法利用不同幅值的M周期序列作为系统的输入，通过DFT变换，离析出线性子系统的连续模型，并由频域辨识法及时域辨识法直接估计出连续模型的参数和非线性特性的系统。数字仿真结果表明本算法是可行且有效的。 |
| 英文摘要 |
| In this paper, a method for estimating the parameters of continuous Hammerstein model is proposed. The M sequences of different magnitude are used as input signals herein. By means of DFT transforms, an equivalent continuous model of the linear subsystem is analysed and separated from the original. The parameters of the continuous model are directly estimated in both frequency and time domain. The simulation results show that the method is feasible and effective. |
