摘要：A kinetic system with control function and parameter is established to formulate the batch culture process of bio-dissimilation glycerol to 1,3-propanediol (1,3-PD) better.Subsequently,some properties of the kinetic system are proved.Taking the minimal error between the experimental data and calculated values as the performance index,an identification model is presented and it is transformed into a parameter optimization problem by discretization method.The identifiability of parameter is also proved.Finally,an improved particle swarm algorithm is constructed to solve the optimization problem.Numerical results show that the errors between the experimental data are cut down by 6%-16%and the kinetic system can characterize the batch culture process better.
