Neural Network Based Modelling and Prediction for the Coating Weight of HDGL Process

Zai-Sheng Pan  Tian-Lin Wang  Shao-Liang Wang  Peng Chen  
【摘要】:To deal with the difficulties of large time-varying delay,seriously nonlinear and strong disturbance in the hot-dip galvanizing line(HDGL) control,this paper proposes a novel ANN based modelling and prediction method for the coating weight,the proposed method is then applied to a real plant at Valin LY Steel Co.,Loudi,China.The prediction model is built through data pre-processing,data clustering and model training,with the model deviation being corrected through bias-update.The comparisons between measured coating weight and model prediction of a real HDGL process show the effectiveness of the proposed method,and the rationality of the prediction model is further verified though gain analysis between major input and output of HDGL process.
