| Abstract: | The nonlinear impulsive system of microorganism fed-batch culture is presented in this note. Then the identification model (PDP) is given for some sensitive parameters. The relationship between the parameters and the solution of the impulsive system is discussed, and the identifiability of the PDP is deduced. At last the optimal solution of PDP is derived by using the constructive algorithmand the stability of impulsive system for fed-batch fermentation is considered. |
| Keywords: | Stability parameter identification fed-batch culture the nonlinear impulsive system. |
