Research on Energy-saving Pump Speed Regulation Control System

By analyzing principle of the energy-saving pump speed regulation control system,the mathematical model is established.The stability of the system is analyzed by Nyquist stability criterion,and the observability and controllability is judged.The pole assignment is used to improve the performance of the system.The performance is compared by Simulink simulation.By using PLC programming,Wincc flexible combined with touch screen on system configuration,the friendly HMI control is realizes.Results show the followings: The stability of the energy-saving pump speed regulation control system is good,it has good observability and controllability,and the performance of the system is improved by pole assignment.The energy-saving pump speed regulation control system can be precisely controlled is verified by experiment,thus energy-saving speed regulation control of the pump is realized to meet the requirements of industrial production and reduce energy consumption.
