Abstract
A Fuzzy-PID controller is developed in variable frequency constant pressure water supply system to guarantee water supply quality and reduce energy consumption. The variable frequency constant pressure water supply system includes the programmable logic controller (PLC) and its extension block, pressure sensor, variable-frequency Drive, pumps and human-machine interface. Test results show that the proposed fuzzy-PID method outperforms the conventional PID method in the aspects of dynamic response and steady-state error.
