Abstract: In order to improve energy-saving control of urban underground sewage treatment pumps, an optimisation method of energy-saving control parameters of urban underground sewage treatment pumps based on fuzzy parameter adaption is proposed. Firstly, the energy-saving control object model of an urban underground sewage pump is constructed, and the energy-saving parameters of the urban underground sewage treatment pump are adjusted using a first-order linear auto-disturbance rejection controller. Secondly, a speed observer is used to optimise the speed of the energy-saving underground sewage treatment pump. Finally, the load disturbance and parameter perturbation is optimised by constructing a high-frequency buffeting and hysteresis inhibition model. The simulation results show that the method has good adaptability, strong anti-interference ability and robustness for energy-saving control of sewage treatment pumps.

Keywords: underground sewage treatment pump; energy saving; automatic control.
