Abstract: The high-pressure fire water supply system mainly relies on the stabilized pressure system to ensure the flow and water pressure of the most unfavorable point in the pipe network. Therefore, the performance of the stabilized voltage system determines the reliability and stability of the high-pressure fire water supply system. The fuzzy controller has good robustness and high response speed, while the PI controller can eliminate the steady-state error and realize no difference adjustment. In order to improve the stability and reliability of the fire water supply system, a fuzzy- PI dual-mode control model is constructed to deal with the influence of high-pressure fire water system being large lay and non- linear on the fire water network. The experimental results show that compared with the conventional PI control and fuzzy control, the control model has not only simple structure, but also excellent control quality and performance.
