Recursive Estimation of Parameters of Transfer Function Matrix Subsub-model: Instrumental Model Method

本文提出了递推估计传递函数阵子子模型(SSM)参数的辅助模型方法。不同噪信比下的数字仿真结果表明了所提出的算法的有效性。该算法计算量小,且可用于在线辨识。

In this paper a recursive algorithm is presented for on-line identification of the parameters of transfer function matrix subsub-model for linear multivariable systems based on the proposed instrumental model method. The results of simulation with different noise levels show that the proposed algorithm works quite well.The algorithm is computationally efficient and is used for on-line identification.
