The Research for Dissolved Oxygen Experts Fuzzy Control System in Sewage Treatment
The stable control of dissolved oxygen in biological wastewater treatment system is a typical large inertia, the longer lag time and a certain degree of uncertainty in the system. This paper analyzes the process of CAST wastewater treatment technology and establishes a model of dissolved oxygen control. The article analyses the underlying causes in instable control system by step response curve of conventional PID closed-loop system, and gives the design method of experts fuzzy control system. The article also gives the control system simulations under the step signal and the interference signal, and gives the robustness of the system simulation testing. Experts fuzzy control system in biological wastewater treatment has obvious advantages.
