This paper explains and demonstrates how to construct a constant pressure water supply system with an integrated intelligent inverter controller (CPS-20B type) based on fuzzy control. This system can automatically adjust the mode of operation in accordance with different working conditons. The controller can choose the number of working pumps and change the motor speed to achieve constant pressure water supply. The PID regulator is set in the CPS-20B1 controller to adjust the output of the inverter, and the automatic regulating system is formed into a closed loop. The simulation results and practical application show that this system used in the water supply network can keep the water pressure stable. This system has been used in a number of industrial and civil water supply service since 2009, which improved efficiency and saved cost.

In view of the constant pressure water supply system with multi-parameter、non-linear and large delay characteristics, this paper employs PLC and the technology of frequency conversion control, and introduces fuzzy control technology to perform constant pressure water supply. The controller can automatically adjust the parameters online, i.e., according to the different work conditions, the controller can choose the proper control parameter, so that the water pressure regulation in water supply system will obtain effective control. The simulation results and the practical application show that our fuzzy controller achieves competitive performance: the faster response, reduced overshoot, greatly shortened transient time, the fewer oscillation, strong robustness and good stability, which can improve efficiency and bring cost saving.

A new energy-saving method of variable frequency and constant pressure water supply system based on fuzzy control theory and software control technique is presented in this paper. Firstly, collecting the pipe network pressure periodically through the pressure sensor, the differential pressure signal will be sent into fuzzy controller after comparing the pipe network pressure with the set pressure. Then send a precise control quantity into the PID regulator to control output frequency of the frequency converter after a series of fuzzy arithmetic and solution of fuzzy arithmetic, so as to achieve the purpose of pump speed and consumed power controlling. The operating principle of variable frequency and constant pressure water supply system and the design procedures of software programming are elaborated. Practical application shows that the variable frequency and constant pressure water supply system based on fuzzy control has good effect on energy saving and obvious economic benefits and is worth popularizing and applying.
