From the viewpoint of modern control theory, soil-plant-water is concerned with a complicated system. Thus, precision irrigation needs all kinds of advanced techniques to archive high efficiency of water resource. This paper presents an irrigation system, which includes FD moisture sensor, wireless communication, RS-485 bus, remote control and distributed control. In particular, authors developed the complete irrigation system, including soil moisture sensor. Since soil-plant-water is viewed as a time-varying objective, a control algorithm related two-input to one-output for fuzzy model is proposed. As a demo of automatic control in water resource usage, this system has been running for one year to monitor and control irrigation process in a greenbelt of the campus of Beijing Forestry University.
