| Abstract: | In order to deal with time varying and strong nonlinearity of lead - zinc sintering process, an integrated method of predicting synthetic permeability based on neural networks（NNs） and a particle swarm optimization（PSO） algorithm has been developed. Firstly,the model of the exponent of synthetic permeability is constructed. Secondly, NNs are used to establish two models of time sequence and technological parameter for predicting the permeability, and a PSO algorithm is applied to train the NNs so as to improve real - time of the models. Thirdly, a fuzzy classifier is used for combining the two models with an intelligent integrated model for predicting the permeability. Finally, the results of actual runs show that the proposed integrated prediction model possesses high precision and good ability of self - learning. Under the condition of big fluctuation, it still has good effect. |
