Three-Tanks is commonly used in the simulation of industrial process measurement and control of liquid level, flow, temperature, pressure parameters, it has the characteristics of nonlinear, strong coupling, multiple variable and complex lag. An introduction of the structural design principle of micro-three-tanks system, the design of hardware and software is conducted in this paper. Two kinds of liquid level control algorithm is proposed, and experiments have been conducted to verify the control algorithm. The simulation and physical experiment is combined, and remote control can be realized in the system .With compact structure, openness, strong expansion, cost-effective benefits, the system can be used for the design and innovation of experimental teaching in courses, such as the principle of automatic control and computer control technology.
