System Identification Application on the Cold Rolling

The process modelling and process simulation are important tools in the current days, in a special way the system identification generates models in the discrete time domain or in the discrete frequence to describe the system behavior that they can aid in the control process project and in its execution. steel cold rolling process was described initially with traditional techniques. Then, the interesting variables of the system identification process could be obtained. The next step was to model the cold rolling process with these techniques and the models to each roling stands were obtained. These presented better adjustment as the prection of system identification
