| 摘 要： | 设计了基于模糊控制的节水灌溉系统，由作物蒸腾量和土壤水势为输入，以作物需水量为输出，通过对输入变量的模糊化、模糊推理和反模糊化，获得了作物的需水量，采用三星单片机为核心，由作物蒸腾和水势变送器分别测量作物蒸腾量和土壤水势，使用分段模糊控制策略构成灌溉系统。试验结果表明：该系统能快速准确地计算出作物的需水量，有效地实现了节水灌溉。

| Abstract: | A water-saving irrigation system based on fuzzy control was developed. The transpiration of the crops and soil water potential are regarded as input variables and the required-water capacity of the crops is regarded as the output variable. The controlled variable was acquired by fuzzification of input variable, fuzzy inferential and de-fuzzification. The system is based on Samsung MCU. The transpiration and soil water potential were measured by transmitter. The irrigation system is based on the segmental fuzzy control strategy. The results show that the system can calculate the required-water capacity of the crops promptly and fulfill water-saving irrigation. |
