Abstract: Aiming at the dissolved oxygen concentration characteristic in the biofermentation process, combining the application of selftuning fuzzy adaptive PID control theory in predictive control system, the new control system was presented. The system is independent of the mathematic and physical character, has an excellent performance and wonderfully dynamic adaptability. The simulation results show that the control system realizes realtime and optimization control of supply oxygen rate, overcomes the lack of routine PID control in the dissolved oxygen concentration, obtains the aim of optimization control and saving energy sources.
