Brief Introduction of Mathematical Model of Packaging Steel Strip Rolling
　　Mathematical model is a type of model described in mathematical language. The mathematical model can be one or a group of algebraic equations, differential equations, differential equations, integral equations, or statistical equations, or some appropriate combination of them, and can also be curves, graphs, etc. The mathematical model describes the behavior and characteristics of the system (or object) rather than the actual structure of the system. A mathematical model reflects the characteristics of a certain aspect of the object.
　　The mathematical models in the rolling production process are divided into process mathematical models and control mathematical models according to different uses. The establishment of process mathematical models requires the use of process theory knowledge, such as rolling principles and steel rolling technology. This type of model is generally used in process control level computers to calculate the optimal set value. The control mathematical model is generally used in the calculation of the optimal control of the actuator by the basic automation level computer. The control model is mainly designed according to the automatic control theory and the performance requirements of the control system, combined with the specific characteristics of the object.
　　Mathematical models generally appear in the form of mathematical formulas (programs converted into) or tables in computers. The main requirements for mathematical models are simple structure and accurate forecasts, so as to shorten the calculation time of the computer and obtain accurate results, but the two are often mutually restricted. There are many methods for establishing mathematical models, and the processes are also different. Most methods combine theory and experience. However, some complex objects are difficult to model, and there is no corresponding formula to express their characteristics in the current mathematical theories. Therefore, other methods (such as neural network theory, fuzzy control theory) should be used to build models.
