With the continuous increase of energy consumption,the research and design of high-efficiency and energy-saving pump stations have become increasingly important.A fuzzy PID control method was proposed for efficient and energy-saving pump stations.Firstly,a mathematical model of the high-efficiency energy-saving pump system was established.Secondly,based on the application of the backstepping control algorithm in the mathematical model of the pump station,the stability of the system was verified through Lyapunov stability theory.Finally,a mathematical model and backstepping controller of the pumping station system were constructed on the MATLAB/Simulink environment platform,and the backstepping control method was compared with the PID control method.The simulation results verified that the tracking accuracy of the backstepping control method in high-efficiency and energy-saving pumping stations was better than that of the PID control method.According to calculations,the proposed backstepping control method improves tracking accuracy by 61.1% compared to the PID control method.
