Self-Organizing Modelling of Biotechnological Batch and Fed-Batch Fermentations

The paper at hand deals with an approach for the automatic generation of dynamic nonlinear process models. These models are obtained from experimental process data as well as from theoretical biological and chemical reeections using the ideas of Genetic Programming for the supervision and coordination of the symbolic model structure during the automatic development.

Evolutionary Strategy for Feeding Trajectory Optimization of Fed-batch Reactors

Safe and optimal operation of complex production processes is one of the most important research and development problems in process engineering. This problem is the most relevant at the design of the optimal feeding profile of fed-batch chemical reactors due to the nonlinear and unstable dynamical behavior of the processes. This paper shows that how the optimal feeding policy can be determined...

RBF Modelling and Optimization Control for Semi-Batch Reactors

This paper presents a neural network based model predictive control (MPC) strategy to control a strongly exothermic reaction with complicated nonlinear kinetics given by Chylla-Haase polymerization reactor that requires a very precise temperature control to maintain product uniformity. In the benchmark scenario, the operation of the reactor must be guaranteed under various disturbing influences...

Modelling of a Fed-Batch Fermentation Process

This report describes the building of a simulator for prediction of the dissolved oxygen concentration, the oxygen transfer rate and the concentration of carbon dioxide in a fermentation process. The steady state models were made using the linguistic equations method. The dynamic models were made using Simulink ® toolbox in the Matlab ® . At the beginning, some basics about fermentation and mic...
