基于模糊PID算法的肥水灌溉系统
Fertilizer irrigation system based on fuzzy PID algorithm
摘要
Abstract
To achieve precise fertilization in farmland irrigation and meet the demand for fertilizer concentration at different growth stages of crops,a fertilizer irrigation system based on the fuzzy PID algorithm was designed.On the basis of traditional PID control,this system combined fuzzy theory to transform expert agricultural irrigation experience into fuzzy control rules.By using the deviation of fertilizer concentration and the rate of deviation change,the fuzzy logic rules were applied to adjust PID parameters in real time,thereby precisely controlling the electrical conductivity(EC)of the fertilizer solution.In the simulation test of farmland irrigation,the fuzzy PID design controlled by PLC had a shorter response time than traditional PID,reduced the time to reach steady state by 70 s,and exhibited faster reaction speed and better performance,enhancing the precision of the fertilizer irrigation system.关键词
