| Abstract | Rolling force prediction is very important in hot strip rolling mill. But during the setting of rolling force in hot strip rolling mill, the rolling force signal is influenced by various factors with complicated correlation. Therefore, it is difficult to establish an accurate model to describe the rolling mechanism. In order to solve this problem, a multiple-RBF neural network model to predict rolling force based on wavelet analysis is proposed. In the new model, the multiresolution wavelet analysis method is employed to separate the rolling force signal into several sub-signals corresponding to different factors, and several RBF neural networks are established, each for a certain subsignal. Thus, the sub-networks can well reflect the variation mechanism of the rolling force. With real-time data obtained from the production process, the proposed model is trained and applied to the rolling force prediction. Simulation results show that the prediction accuracy is improved, and the average error rate decreases to less than 5%. Therefore, the method is an effective way to build a prediction model of rolling force and has great potential for applications in practice with it's high prediction accuracy and short training time. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
