Static Model Building of Heating Process of Continuous Annealing Furnace

The continuous annealing furnace,as one of the most important equipments in high-grade deep drawing automobile sheets production line,is a nonlinear,time-varying,strong coupling with multi-variable,time-lagged control object.In accordance with the problem that difficult to build an exact mathematic model,based on the gained static model of heating process in a certain continuous annealing furnace,the identification of model parameter and optimization of model structure are performed by using the least-squares method.The program idea of least-square method of static model are introduced.Model identification and Matlab simulation on mass data show the practicability of the methd.The application of the technology increases the precision of model and has enormous guiding significance to enhance the product quality and quantity in the industrial production process.
