Embodiment Construction
[0034] The technical solutions of the present invention will be further specifically described below in conjunction with the accompanying drawings and specific embodiments.
[0035] Such as figure 1 Shown, step a, collecting data. During the rolling process, the historical data collected by the primary machine is stored in the data center, and .mat files (data files readable by MATLAB) are generated through classified collection, and tt_data_*.mat files are generated. In order to make the data representative, if the coefficient is for the steel family or steel type, at least 2000 coils of the same steel family or steel type must be taken, generally 4000 coils; if the global coefficient optimization is selected, there is no need to distinguish steel type.
[0036] Step b, data denoising. In order to improve the reliability of the data, preprocess the selected data, and use simple statistical methods to remove the noise in the data, that is, unreliable data, such as data afte...
