一种多变量系统辨识法及其在蒸发过程的应用
Multivariable processes identification and its application in evaporation process
摘要
Abstract
A new identification method for multivariable plus time delay mode is proposed to effectively analyze the evap-oration loop in molecular distillation system. An idea of transforming MIMO identification into SISO identification is used to simplify the identification, and the basis of the idea is proven. An equation set is constructed by the response data of the process with step input, and the unknown coefficient of the equation set is obtained by using the Simpson numerical integration formula. The transfer function matrix is obtained by solving equation set mentioned above. The feasibility and estimate precision of the proposed algorithm have been demonstrated through a number of simulation examples and experiments.关键词
