摘要
采用带动量项的线性再励自适应变步长BP神经网络算法,建立了基于多周期运行模式的烧结矿化学成分预报模型;使用基于数据库技术的知识库和正向推理的推理机,开发了化学成分控制专家系统.系统自投入运行以来,预报模型命中率稳定在90%以上,操作指导建议采纳率达到92%,实现了对烧结矿化学成分的稳定控制.
A sintering predictive model of chemical composition based on many periods was developed by the BP neural network algorithm with appending momentum and adaptive variable step size linear reinforcement. Using knowledge base that was based on database technology and illation with forward inference, an expert system was designed for controlling sinter chemistry. Since the system was plunged into application, the hit ratio of the predictive model is over 90% steadily, and the acceptance of operation suggestion is 92 %. The goal of controlling chemical composition steadily is actualized.
