Recursive Identification and Realization Algorithm of Input-output Bilinear Systems

本文对输入输出双线性系统给出了一套完整的辨识方法。首先给出了输入输出方程的一般形式,并对于一类规范型给出了相应地输入输出差分方程。然后给出了确定系统的结构指标和参数估计的递推算法,它改进了由Katta和Nurges(1984)给出的方法,大大缩短了计量时间。另外,还给出了状态方法的简单实现算法。最后,给出了仿真例子说明算法的有效性。

In this paper a complete identification method for input-output bilinear systems have been proposed.First, the general form of input-output equation has been given and a input-output difference equation corresponds to a class of canonical form has been obtained. Second, a recursive algorithm of the structural indices and the paramters identification has been proposed, and the realization algorithm has been given. Finally, the simulation example is given.
