High-rise Constant Pressure Water Supply Control System Based on Fuzzy PID

Abstract

∗Constant pressure water supply system has the characteristics of non-linearity, large inertia and large lag, so it is often difficult to establish an accurate mathematical model. The traditional PID control method is not flexible enough to achieve better control effect. In order to improve the stability and efficiency of water supply system, a variable frequency constant pressure water supply system based on fuzzy self-tuning PID is designed and simulated in Simulink environment of MATLAB. The experimental results show that the application of fuzzy PID control in water supply system shows good control effect, strong adaptability, stability and reliability, energy saving and environmental protection.
