The soft-sensing and optimal control of microbial fermentation process
has become an important research content in the biotechnology field. It
is of great significance to improve the level of equipment automation,
promote the innovation of biotechnology technology, improve production
efficiency and economic efficiency.In this book, the inverse soft
sensing model of fermentation process is constructed by combining
inverse system method and least square support vector machine
theory(LS-SVM), LS-SVM is used to approximate the nonlinear function
which is difficult to express explicitly in the inverse soft-sensing
model, and the support is established. Secondly, in order to realize
decoupling and optimal control of multivariable nonlinear systems, the
inverse control method of LS-SVM is proposed, and the inverse system
method is combined with IMC. A new method of internal model control for
inverse system based on LS-SVM is proposed, which improves the
robustness and anti-jamming ability of the inverse control method.
Furthermore, the theoretical results are applied to the development of
engineering software, and good results are obtained.
