| 中文摘要 |
| 加热炉在钢铁企业发挥着非常重要的作用. 在加热炉中部分生产过程数据较难检测, 部分检测到的数据受到严重干扰和缺失, 这严重影响了加热炉的优化和控制, 而且还存在潜在的安全隐患. 本文针对加热炉这一复杂的过程, 设计了一个生产过程数据预处理系统. 该系统能对部分难以测量的数据用自适应模糊神经网络(FNN)方法进行预测, 能对过程数据进行滤波和正误判断, 能对异常数据进行剔除和替代, 并对过程数据替代值利用案例推理(CBR)方法建立完善机制. 该系统在某钢铁公司进行了实际应用, 取得了明显的应用效果. |
| 英文摘要 |
| Because of the complex environmental interferences, the operation data of a heating furnace is disturbed or even lost in measuring; this deteriorates the accuracy and stability of the control system, or even causes potential security risks in production. To deal with this problem, we propose a preprocessing system for the operation data of a heating furnace. It employs the self-adaptive fuzzy neural network (FNN) method to predict the immeasurable data, provides the data-filtering, and rejects abnormal data by case-based reasoning. It uses the case-based reasoning (CBR) method to build a new mechanism for data replacement and modification. This intelligent preprocessing system has been successfully applied to a heating furnace in an iron-and-steel company, achieving desirable production results. |
