Because a single mannequin can't symbolize the traits of the complicated industrial manner in various running ranges,we recommend an on-line modeling scheme for more than one models.This scheme consists of the awareness mechanism of running range,the neighborhood fashions and the aggregate mechanism for a couple of models.The focus mechanism analyzes the running vary in accordance to its attribute variables and adjusts the middle of running vary in accordance to similarity degrees.The nearby mannequin is absolutely a Hammerstein mannequin which is the serial connection of a wavelet neural community with a secure gaining knowledge of algorithm and an ARX model.The mixture mechanism calculates the weighted sum of the outputs of neighborhood models,and on-line adjusts the facilities of running vary to mirror the variant traits of the running range.A secure mastering algorithm of parameters improves the prediction accuracy and the adaptation ability.This technique is implemented in a wastewater remedy manner to measure the attention of the chemical oxygen demand(COD).Experimental consequences exhibit that this modeling scheme can achieve best impact in various running ranges.
