Modeling 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 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 کاملAn Improved Nonlinear Complex System of Microbial Bioconversion Process in Fed-batch Culture
The purpose of this paper is to explore the properties of a new model which can describe the multistage of population growth of microorganisms. The improved model is developed based on the time dependent changes of the specific growth rate. Considering the discontinuity of the process of adding glycerol and alkali, a nonlinear complex kinetic system(CKS) of fed-batch fermentation is investigate...
متن کاملModelling 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...
