基于模糊控制的节水智能灌溉系统设计

Design of Water-saving Intelligent Irrigation System Based on Fuzzy Control

中国是农业大国,在由农业大国向农业强国转变的道路上,农业灌溉用水量是迫切需要解决的问题。由于土壤含水率是一个复杂的非线性的变化过程且灌溉系统难以建立一个精确的数学模型,因而设计了基于模糊控制的节水智能灌溉系统。该系统以土壤水分误差和误差变化率作为输入量,灌溉时间为输出量,模糊规则以专家经验为基础设置,最后通过Matlab仿真验证,表明该系统可以有效地实现节水智能灌溉的功能。

As China is a large agricultural country,water consumption for agricultural irrigation is an urgent problem to be solved on the road of transforming into a powerful agricultural country.Because the soil moisture content is a complex nonlinear change process and it is difficult to establish an accurate mathematical model for the irrigation system,a water-saving intelligent irrigation system based on fuzzy control is designed.The system is based on soil moisture error and error rate of change as input,irrigation time as output,fuzzy rules set on the basis of expert experi⁃ence,and finally through Matlab simulation verification,shows that the system can effectively achieve the function of water-saving intelligent irrigation.
