Design of fuzzy controller for activated sludge process in sewage water treatment system

하수처리 시스템에서의 활성오니공정 제어를 위한 퍼지제어기 설계

The activated sludge process is a commonly used method for treating sewage and waste waters. The process is characterized by a lack of measurement instrumentations and control goals that are neither well defined nor well understood. In the present study the concept of fuzzy control is employed for such process in which a design method for fuzzy controller based on a multivariable fuzzy reasoning algorithms is investigated and then simulation results are presented.
