摘要
提出了一种开关控制与模糊控制相结合的双模控制算法,适用于以土壤含水率为被控对象的灌溉控制系统,属于自动闭环控制。此算法应用于自主研发的低成本节水灌溉控制系统进行测试,结果证明该算法能有效控制土壤含水率,可以适时适量灌溉,达到了精准灌溉的要求。同时该算法使得灌溉系统不仅节约了水资源,还节省了人工维护成本。
A dual-mode control algorithm based on on-off control and fuzzy logic control was proposed to enable the irriga- tion system to realize an antomatic closed-loop control. The algorithm was tested on low-cost water-saving irrigation control system. The results showed that the algorithm could effectively control the soil moisture content, timely satisfy precision irriga- tion requirements. The algorithm can enable the irrigation system to save water resources and reduce the cost of artificial maintenance.
