Combined with the practical situation of Nosiheptide fermentation process
a weighted radial basis function neural network (WRBFNN) based biomass soft sensor modeling method is presentedBased on the unstructured model of Nosiheptide fermentation process
the secondary variables were selected according to the implicit function existence theorem
which made the selection theoretically strictAccording to the characteristics that biomass could vary in a wide range
the error function of the traditional RBFNN was improvedEach batch sample was selfadaptively weighted according to their predicting ability to the predicted object
and then WRBFNN was used to develop the biomass soft sensor modelThe testing results showed the effectiveness of the presented approach.
