摘要
以农田喷灌系统为研究对象,综合考虑农田土壤温度与土壤湿度,基于区间数学控制算法建立了一种模糊控制喷灌控制系统。以土壤温度和湿度为控制目标,通过农田喷灌来达到目标控制;综合运用土壤温度与土壤湿度的隶属度关系函数曲线,给定不同隶属度条件下的系统控制规则,模拟土壤温度与土壤湿度,进行控制系统的仿真模糊合成计算,确定出喷灌的时长函数,并进行土壤温度和土壤湿度的对比,得出偏差量,形成相关迭代控制过程。系统可实现农业生产过程中土壤湿度的定量控制,促进了土地灌溉的自动化和智能化。
In this paper, a fuzzy control sprinkler irrigation control system is established based on interval mathematical control algorithm, taking the farmland soil temperature and soil moisture into account. Taking soil temperature and humidity as control objective, the target control is achieved by sprinkler irrigation in farmland. The membership function curve of soil temperature and soil humidity is synthetically used. The system control rules under different membership conditions are given. The soil temperature and soil humidity are simulated. The simulation fuzzy synthesis calculation of the control system is carried out to determine the time-length function of sprinkler irrigation, and the soil temperature is calculated. Comparing with soil moisture, the deviation is obtained and the related iterative control process is formed. Achieving the quantitative control of soil moisture in agricultural production and promoting the automation and internalization of land irrigation.
