| Abstract: | In sewage treatment system,dissolved oxygen concentration plays a vital role.In view of the importance and the control requirements that the dissolved oxygen concentration in the CASS pool in wastewater treatment system,proposed a method of BP neural network and designed the BP neural network controller.Through the training of BP network model and simulation,we know that BP neural network obtained a high degree of accuracy and reliability with the control of dissolved oxygen concentration.Finally,the combination of this BP network controller and PLC were used in the real system,the control of dissolved oxygen concentration to achieve the desired results. |
