Design and Implementation of Sewage Treatment Control System Based on PLC and Fuzzy Control Technique

The importance and complexity of dissolved oxygen control during the bio-oxidation process of sewage disposal were discussed.To control the dissolving oxygen while controlling sewage disposal based on the use of fuzzy control method,we designed the fuzzy control system of the dissolving oxygen based on PLC,and carried out the computer simulations to the result,and proved the validity of the control system.The paper put forward some shortcomings on fuzzy control.In view of these deficiencies,the novel neural network fuzzy control scheme was proposed finally,which has offered a new design method for automatic control of sewage disposal.
