Self-organizing Structured Modelling of a Biotechnological Fedbatch Fermentation by Means of Genetic Programming

. The article at hand describes an approach for the self-organizing generation of models of complex and unknown processes by means of genetic programming and its application on a biotechnological fed-batch production. Key Words. Genetic programming; modelling; system identification; biotechnology; predictive control. 1. INTRODUCTION The natural biological metabolism of living organisms can be used for the production of food, medicines or basic materials for the chemical industries. The major task for optimization of those biotechnological processes is to overcome natural limitations by genetic manipulation of the organisms or variation of environmental conditions during the fermentation. This variation is part of the process engineers tasks and can be achieved by the use of advanced intelligent methods of control engineering. Almost any approach for the design of control systems is based on a model of the process behaviour. In predictive control systems -- fig. 1 --, which have prove..
