【Abstract】 The fermentation process of yellow rice wine is very complex, and it is difficult to establish an accurate mathematical model. When traditional PID controller is used for temperature control, the accuracy is not high, the response to problems is slow, and it need long time to adjust the parameters. Therefore, this paper proposes fermentation temperature control strategy before yellow rice wine based on the BP neural network, using the PID controller to adjust parameters, to improve the performance, and builds a dynamic simulation model. The simulation results show that the PID controller designed has higher control accuracy and faster response speed and the coupling interference is effectively improved.更多还原
