Application of Fuzzy Control in Sewage Treatment System

Fuzzy control does not need to master the precise mathematical model of control object, but to determine the amount of the control object according to the control rules. This control method has a good control effect for the system with lag or random interference. It is a new attempt to treat the sewage with a PLC fuzzy controller. The control system is more reliable and it could achieve a good control effect. According to the features of the complexity of modern sewage treatment system and the difficulty of establishing accurate mathematical model, a fuzzy control method applied to the system with PLC is established and realized. The results showed that based on this method, the system is easy to realize and anti-interference ability is strong, a good adjustment quality is obtained.
