Black-box model identification for a drum of steam boiler based on Hammerstein-Wiener model

Abstract-In this paper, one black-box model identification method based on Hammerstein-Wiener model is presented for modeling a drum of steam boiler .In this method, the system is considered as a black box of which it is not necessary to know structures and parameters inside.A nonlinear system identification, which is composed of nonlinear blocks and linear blocks, has been processed and synthesizd yielding the modeling from only measured inputs and outputs of the system. Comparison between the responses of the proposed models with the responses of the plants and mathematical model validates the accuracy and performance of the modeling approach.
