Abstract :
A novel modified differential evolution (MDE) algorithm that contains simplex acceleration operator and chaotic migration operator is proposed for feed rate optimization of fed-batch fermentation process. The simplex acceleration operator improves the speed of getting global optimum, and the chaotic migration operator keeps the individualspsila diversity in the population to overcome prematurity. Three selection rules are introduced into the algorithm for constrained optimization problem, which ensures that the solution could accord with the constraint condition. The modified algorithm is applied to optimize feed rate of a certain fed-batch fermentation process, which improves the final product yield. The results show that the algorithm is effective.
