Study on soft sensor for lysine fermentation based on BP neural network

The key biological parameters (such as germ density, matrix density, product density)are hard to measure real-time online in biological fermentation process. Applications are great limited to the biological fermentation process in the advanced control technology. A BP neural network soft-sensor model is given based on lysine fermentation process in this paper, Experiment and simulation conclusions of lysine key parameters can be measured on-line, and achieve a higher accuracy.
