Abstract

With the rapid development of intelligent buildings, a lot of researchers have found that it is difficult to establish mathematical model when the problem that energy-saving in water supply system of an intelligent building tank is focused, because that the outflow of the tank volume is volatile when the water is daily living water. In this paper, fuzzy control theory is used to establish a fluid level, and the fluid input flow rate to determine the amount of control, which to push the valve’s opening size and speed in order to control the water supply valve opening adjustment level, so that the liquid position of container maintains a constant, and the MATLAB software is used to verify the effect of fuzzy control system. The results show that in this fuzzy control system the benefits of economic operation of water supply can be ensured by ensuring a constant level of liquid.
