中文摘要
      本文讨论带有观测噪声的多输入多输出（MIMO）线性循环（cyclic）系统的辨识问题。利用循环系统特有的性质，本文提出了一种相关函数——增广矩阵递推辨识算法，一次辨识出系统的阶数和参数，从而避免了逐一辨识系统结构指数的复杂过程。计算机模拟算例表明，本文提出的算法是有效的。
英文摘要
      In this paper the problem of the identification of linear discrete multivariable cyclic system from noisy measurements is investigated. Based upon the characteristics of cyclic system, a method for identifying the order and parameter matrices of the system is obtained. The order of the system is directly obtained with a recursive algorithm using the correlation functions of a linear combination of the outputs. The parameter matrices are estimated by using a recursive algorithm involving extended matrices. Computer simulation shows the applicability of the proposed method.
