Abstract

The invention relates to a secondary water supply system and the automatic control field, in particular to a network pressure superposition water supply system based on optimal auto disturbance rejection control. The system comprises a transducer, an asynchronous motor, a water pump, a pressure sensor and a digital control unit based on auto disturbance rejection algorithm; wherein the digital control unit based on auto disturbance rejection algorithm receives the pressure value input by a pressure sensor and outputs the pressure value to the transducer in the form of analog voltage signal after A/D conversion and processing of internal auto disturbance rejection program; the output terminal of the transducer is connected with the input terminal of the asynchronous motor, the asynchronousmotor adjusts speed according to the voltage and frequency signal given by the transducer, thus regulating the exit pressure of the water pump. The invention has the beneficial effects that: the control problem of the existing network pressure superposition water supply system is solved, thus improving performances of response speed, anti-interference ability, robustness and the like of the systemand improving safety of water supply and comfort of user water.

Description

technical field [0001] The invention relates to the field of secondary water supply system and automatic control, in particular to a pipe network superimposed water supply system based on optimized active disturbance rejection control. Background technique [0002] With the advancement of science and technology and the development of society, the water supply and drainage equipment has experienced from the traditional water pump pressurized roof water tank to the more common frequency conversion constant pressure water supply system. At the end of the 20th century, a new type of water supply equipment appeared. water supply system. The system is developed on the basis of frequency conversion and constant pressure water supply system. It not only inherits the advantages of frequency conversion and constant pressure water supply, but also makes full use of the residual pressure of the pipe network to reduce energy waste; in addition, large volume equipment such as pools and ta...
