摘要：
A method of fault diagnosis based on composite model and support vector machines for fermentation process is proposed to overcome its difficulty in direct measurement of state parameters. In order to obtain the process state, composite model is presented by combining mass equations of bioreactors with RBF neural network that serve as estimators of unmeasured process kinetic parameters. Then Support vector machines are used to analyze and recognize fault patterns, making use of estimated state variables on line. The proposed method is applied to glutamic acid fermentation process, and the simulation results show its feasibility and effectiveness.
