The study of fuzzy PID control of dosing pump in sewerage system

Taking the practical needs for treating sewage resulting from cleansing recycled mulching films in Xinjiang into consideration, the study designed self-adaptive fuzzy PID controller for dosing pump in sewerage system based on the combination of PLC and MATLAB simulation software, and explained the structure of this system and its control principle, with a focus on control strategy and the determination of relevant parameters. This experimental study found that the sewerage system adopted this method is able to achieve a better dynamic and static property, improve the quality of sewage treated while decreasing operating cost.
