状态空间子空间方法处理闭环系统辨识(英文)

Subspace State Space Approach to Closed Loop System Identification

本文给出一个由闭环数据辨识状态空间模型的算法．此算法可辨识带有严重噪声干扰和延迟的稳定及不稳定系统。

In this paper, we present an algorithm to identify state space models based on the data obtained from closed loop systems. It works well on both stable and unstable system with serious noises and large delays and also is proved mathematically.
