双线性系统的一种小样本辨识方法

An Identification Method of Bilinear System Under Small Samples

本文提出了双线性系统的一种小样本辨识方法。辨识步骤如下:首先从系统的零状态响应推出外部描述模型,然后通过小样本线性系统的一种有效辨识方法ESML来估计其参数,最后从被估计的外部描述模型实现成内部描述模型。仿真表明了该法的有效性。

In this paper, an identification method of bilinear system under small samples is proposed. The identification procedure is the following: at first, the external description model is derived from the zero-state response of the systems, then the parameters in the model arc estimated through the ESML which is effective method of parameter estimation for the linear dynamic system under small samples. Finally, the internal description model is realized by using the previous estimated parameters. The effectiveness of the proposed method is shown by simulation.
