Multilayered mathematical model system for hot continuous rolling process control and its application in real process

摘要

A hot continuous rolling process control system, a complex system, has a unique mathematical model system, which is discussed. The system has many complicated methods to deal with large quantities of information from the real process. The models, defined to be in three layers, underlie the whole model system of the control process of hot continuous rolling. The accuracy of the models has close connection with the technological goals-the core of the process control by which the models are combined with each other. Upgrading the accuracy of the models, especially the online models, is probably the short way to improve the control accuracy. An example is also presented.
