Three-tank water tank is one of the most extensively used and representative industrial mathematical models, which has very important research significance. Liquid level control is one out of a multitude of useful used means in industrial check on. Due to the influence of factors such as the friction of the liquid itself, the control object has certain hysteresis and nonlinear characteristics. PID control is one of the most wide-ranging applied control algorithms and its wide operating range and simple function. In this paper, the modeling and simulation of representative three-tank PID and the traditional PID control and fuzzy PID control are compared and summarized.
