Description

technical field [0001] The invention relates to an automatic correction method for a mathematical model of a rolling process, in particular to an efficient adaptive method for a mathematical model of an aluminum cold rolling mill applied in a process control system. Background technique [0002] In most domestic aluminum cold rolling mills, the production process is relatively flexible, and the rolling passes have various specifications. Due to the lack of high-precision mathematical models and adaptive methods, the prediction accuracy of rolling parameters is difficult to meet the requirements of rolling process and equipment conditions, which restricts the improvement of aluminum strip production stability, production efficiency and product precision. With the development of computer control technology, the equipment technology level of aluminum cold rolling mill is getting higher and higher. Improving the prediction control accuracy of rolling parameters has important pra...
