摘要
对污水处理生物氧化过程中溶解氧控制的重要性及复杂性进行了讨论;为了用模糊控制方法控制污水处理中溶解氧,设计了基于PLC的溶解氧模糊控制系统,并对结果进行了计算机仿真,证明了该控制系统的有效性;最后针对模糊控制的不足之处,提出了基于神经网络的模糊控制,为污水处理的自动控制提供了一个新的设计方法。
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.
