摘要
针对目前石墨化炉控温精度不高,时有裂纹废品出现的现状,为提高石墨电极质量,实现石墨化炉的精确控温问题,提出了石墨化炉神经网络预测控制策略。利用径向基函数神经网络建立了石墨化炉稳态模型;利用工业过程裸模化方法,建立了石墨化炉的动态模型,为进一步实现石墨化炉的神经网络预测控制,完成了至关重要的第一步。该石墨化炉神经网络模型,计算机仿真结果非常理想,拟和精度很高,完全可以作为下一步实现预测控制的模型。
At present, the accuracy of controlling the temperature in graphitizing furnaces is not high, and there are several wasters with flaws ustoally. One approach is presented that adapts predictive control based neural network to control the temperature of graphitizing furnace. The approach is for improving the electrode quality and making precise temperature control. The static model of graphitizing furnace is maked using RBF network and finished the dynamic model of graphitizing furnace using the industrial process bare model method. The first important step of predictive control based neural network of graphitizing furnace has been finished. The model has obtained very good simulation result on comput- ers. The precision of the model is very satisflng.
