Szukana fraza: [Abstract = "The model was developed in the Matlab\/Simulink package. There are two common problems associated with the modeling of dynamic systems. If an analytical model is chosen, it is very costly to determine all model parameters and that often prevents this approach from being used. If a data model is chosen, one does not have a clear interpretation of the model parameters. The paper uses the so\-called grey\-box approach, which combines first\-principle and data\-driven models."]
