Modelling and Optimal Control for Nonlinear Multistage Dynamical System of Microbial Fed-batch Culture
In this paper, we propose a new controlled multistage system to formulate the fed-batch culture process of glycerol bio-dissimilation to 1,3propanediol (1,3-PD) by regarding the feeding rate of glycerol as a control function. Compared with the previous systems, this system doesn’t take the feeding process as an impulsive form, but a time-continuous process, which is much closer to the actual cu...
متن کاملModeling and optimal control of a nonlinear dynamical system in microbial fed-batch fermentation
The mathematical model and optimal control of microbial fed-batch fermentation is considered in this paper. Since it is decisive for increasing the productivity of 1,3propanediol (1,3-PD) to optimize the feeding rate of glycerol and the switching instants between the batch and feeding processes in the fermentation process, we propose a new nonlinear dynamical system to formulate the process. In...
متن کاملOptimal Control for Multistage Nonlinear Dynamic System of Microbial Bioconversion in Batch Culture
In batch culture of glycerol biodissimilation to 1,3-propanediol 1,3-PD , the aim of adding glycerol is to obtain as much 1,3-PD as possible. Taking the yield intensity of 1,3-PD as the performance index and the initial concentration of biomass, glycerol, and terminal time as the control vector, we propose an optimal control model subject to a multistage nonlinear dynamical system and constrain...
متن کاملModeling nonlinear stochastic kinetic system and stochastic optimal control of microbial bioconversion process in batch culture∗
Abstract. In this paper, we analyze a stochastic model representing batch fermentation in the process of glycerol bio-dissimilation to 1,3-propanediol by klebsiella pneumoniae. The stochasticity in the model is introduced by parameter perturbation which is a standard technique in stochastic population modelling. Thus, based on the nonlinear deterministic dynamical system of glycerol bioconversi...
متن کاملModelling and Regularity of Nonlinear Impulsive Switching Dynamical System in Fed-Batch Culture
and Applied Analysis 3 According to the factual experiments, we make the following assumptions. H1 The concentrations of reactants are uniform in reactor, while time delay and nonuniform space distribution are ignored. H2 The feeding media includes only fixed concentrations of glycerol and alkali. In the laboratory, the effect of alkali feeding on the pH value is much bigger than the effect of ...
