针对含有异常值观测噪声的EIV模型,提出了一种子空间系统辨识算法。利用最小协方差行列式(MCD)对离群点进行辨识和剔除,然后应用经典的EIV子空间系统辨识算法得到状态空间模型。为了解决EIV模型的MCD问题,我们提出了一种随机搜索算法。该算法已应用于某换热器的数据处理。
In this paper, we develop a subspace system identification algorithm for the errors-in-variables (EIV) model subject to observation noise with outliers. By using the minimum covariance determinant (MCD), we identify and delete the outliers, and then apply the classical EIV subspace system identification algorithms to get state space models. In order to solve the MCD problem for the EIV model we propose a random search algorithm. The proposed algorithm has been applied to a heat exchanger data.
