Optimal Control And Steady-state Optimization Of Enzyme-catalyzed Dynamical System In Glycerol Bio-dissimilation Process

1,3-propanediol is a chemical raw material,which has a wide range of applications.Recently,the mathematical modeling,optimization and control of the yielding of1,3-propanediol by glycerol bio-dissimilation have also attracted more and more attention.In this paper,the optimal control and steady-state optimization of enzyme catalytic dynamical economy in glycerol bio-dissimilation process are studied.For these issues,several optimal control and steady-state optimization models are established,and optimization methods are designed to solve them.The research substance and outcome of this thesis are fall into three sections:1.According to the enzyme-catalyzed nonlinear flow plus dynamic system in the glycerol bio-dissimilation process,this thesis set up three optimal control molds.The nonlinear kinetics economy is transformed into algebraic equations due to the finite element distribution way,and the nonlinear planning shape of the optimal control mold is acquired.The best value of every variable and target function in the optimal control issue is given at different end office,and the results are talk over and analyzed.2.According to the enzyme-catalyzed nonlinear flow plus dynamic system in the glycerol bio-dissimilation process,in the case of fixed terminal time,the optimization objective is to maximize the concentration of 1,3-propanediol and minimize the concentration of glycerol at the end of the cell,established bi-objective optimal control mold.Based on Normal Boundary Intersection(NBI)framework and Collocation on finite elements method,the settle way is devised to seek out the best solution,and inspect the outcome.3.According to the enzyme-catalyzed nonlinear continuous power system in the glycerol bio-dissimilation process,a bi-objective steady-state optimization mold that can rise the yield of 1,3-propanediol and the conversion of glycerol is provided.Based on the Normal Boundary Intersection(NBI)framework,a hybrid optimization arithmetic is proposed for the bi-objective steady-state optimization issue,and contrast the consequence with the published thesis.
