A Study on the System Identification of Cold Tandem Mills using the Subspace Method
부분 공간법을 이용한 연속 냉간 압연기의 시스템 규명에 관한 연구
Abstract
This paper charcterizes dynamics of cold tandem minns, and constructs it state-space model of which are linear time invariant, using subspace method. Step responses particularly show the influence on mass transfer delay. Input-output data set are obtained form nonlinear differential equations including mass transfer delay and nonlinearity. It is shown that the identified state-apace model well approximates the original systems dynamics.
