Abstract: A new way of model building for identification based on RBF neural networks in the penicillin fermentation process was presented .The penicillin fermentation process is a process of time varying and nonlinear feature .RBF neural networks have the ability to get a nonlinear function. Genetic algorithms were used to train the neural networks .A simulation was made to prove this fermentation model . The result of the simulation shows that the model is practicable.
