本文采用了相关分析最小二乘两步法(COR—LS)和两种辅助变量法(IV—A,IV—B),对一台五万千瓦机组锅炉蒸汽过热器进行了闭环辨识.建立了蒸汽过热器单输入——双输出模型,并通过数字计算机仿真和模拟计算机仿真,对不同辨识方法作了比较。
In this paper, a closed-loop identification of the steam superheater of a 50,000-kilowatt boiler was carried out by using the correlation analysis least-squares two-step method (COR-LS) and two auxiliary variables (IV-A and IV-B) Steam superheater single input - dual output model, and through the digital computer simulation and simulation of computer simulation of different identification methods were compared.
