基于GA-Fuzzy-PID算法的棉田施肥灌溉系统研究
Study on Cotton Field Fertilization and Irrigation System Based on GA-Fuzzy-PID Algorithm
摘要
Abstract
In the integrated water and fertilizer controller,the PID control algorithm is easy to cause overshoot and oscilla-tion;Fuzzy-PID control algorithm is not delicate because its parameters are set based on human experience.In view of the above problems,this paper studies and designs a controller based on GA-Fuzzy-PID algorithm,in order to achieve the precise control of fertilizer irrigation system.Under different target EC setting values,the PID algorithm,Fuzzy-PID algorithm and GA-Fuzzy PID algorithm are simulated and compared.The results show that the controller based on GA-Fuzzy-PID has excellent control effect and can better meet the requirements of precise control of fertilizer irrigation sys-tem.关键词
