Design of Fuzzy ADRC Method for Hydraulic Dredging Pumps Used in Hydraulic Engineering
The hydraulic dredging pump used in hydraulic engineering is affected by step load disturbance,resulting in a decrease in the dynamics and power stability of the hydraulic cylinder inflow and outflow,leading to a decrease in the efficiency of dredging.In order to effectively improve the efficiency of hydraulic dredging pump and reduce the impact of step load disturbance,a fuzzy auto dis-turbance rejection control(ADRC)method for the hydraulic dredging pump in hydraulic engineering is proposed.Firstly,it is deter-mined that the relevant influencing factors are in the ADRC process of the hydraulic dredging pump;Then,based on the analysis re-sults of the influencing factors,the fuzzy ADRC control process of the hydraulic dredging pump is determined to control the influen-cing factors;Finally,the fuzzy ADRC of hydraulic dredging pump used in hydraulic engineering is realized.The simulation results show that the load disturbance value of the hydraulic dredging pump obtained by this method is close to the actual load disturbance value,and can accurately estimate the step load disturbance;After controlling the hydraulic dredging pump used in water conservancy projects,the hydraulic dredging pump has a fast response speed,with the silt content of about 0.030 L/min and the volumetric effi-ciency of 98.73％.The results show that this method has a good control effect,and the controlled hydraulic dredging pump has a high stability in hydraulic engineering.
