基于GA-Fuzzy-PID算法的棉田施肥灌溉系统研究OA北大核心
Study on Cotton Field Fertilization and Irrigation System Based on GA-Fuzzy-PID Algorithm
在水肥一体控制器中,PID控制算法易引起超调,产生振荡;Fuzzy-PID控制算法由于参数基于人为经验设定,控制欠细腻.针对上述问题,研究并设计了一种基于GA-Fuzzy-PID算法的控制器,以期实现施肥灌溉系统的精准控制.在不同目标EC设定值下,对PID算法、Fuzzy-PID算法和GA-Fuzzy-PID算法进行仿真对比.结果表明:基于GA-Fuzzy-PID的控制器具有优异的控制效果,更能满足施肥灌溉系统精准控制的要求.
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.
