(英) Error Analysis of Subspace Identification Method in Closed Loop Environment

(日) 閉ループ環境における部分空間同定法の誤差解析

(英) This paper analyzes the estimation error of B and D matrices in closed-loop environment which are estimated by using OE-PIV method proposed by Chou and Verhaegen. Estimates of A and C matrices in closed-loop environment which are obtained by applying PO-MOESP method in the framework of direct method of the closed loop identification has no asymptotic bias and their estimation error can be derived in the previous paper. In this paper, the relation between the estimation error of (B,D) and the estimation error of (A,C,K) are derived.
