| Abstract:
|
Fermentation processes are characterized by a complicated structure of organization and interdependent characteristics, which determines their nonlinearity and non-stationary. Their specific peculiarities predetermine the elaboration of some new methods and approaches for the modelling and control of such processes. A new approach for modelling of considered processes, based on the apparatus of Generalized Nets (GN), is presented in this paper. Generalized Nets provide the opportunity to describe the logic of the fermentation process modelling. Generalized Net models are obtained for batch, fed-batch and continuous modes of fermentation processes. The GN-model for fed-batch operational mode is described in details. The GN-models of batch and continuous modes are obtained by a less number of changes in basic GN-model for fed-batch mode. The facility of models obtaining demonstrates the flexibility and the efficiency of Generalized Nets as modelling tool.
