曝气池混合液浓度的模糊控制

Fuzzy-logic Control of the Mixed Liquid's Concentration

曝气池混合液浓度是影响污水处理水质的一个重要参数。由于活性污泥法是复杂的生物反应过程 ,无法用数学模型加以准确描述 ,所以采用了模糊控制方法来解决混合液浓度的控制问题。

The mixed liquid's concentration is one of the most important parameters effecting the quality of the treated wastewater.The activated-sludge process is a complicated biological process,which cannot be described exactly by a mathematical model.So a fuzzy-logic control strategy is proposed and realized.Both the rules of fuzzy-logic and the structure of control system are presented.
