Biotechnological processes have very large application in very different fields such as food industry, pharmacology, environmental application and etc. They are characterized by a complicated structure of organization and independent characteristics, which determine their nonlinearity and non-stationary. In many cases, the globally valid conventional numeric models, which describe the overall process behavior cannot be used in on-line monitoring and control, either because they do not describe the process well enough or contain too many poorly known parameters. In this book a multiple-model...
