滴灌棉田节水灌溉系统控制策略研究
Study on the Control Strategy of Drip Irrigation Cotton Field Water Saving Irrigation System
摘要
Abstract
A cotton field water-saving irrigation control system based on Fuzzy-PID control is designed to address the problems of low irrigation accuracy and poor operational stability of traditional cotton field water-saving irrigation sys-tems.The system collects the real-time soil moisture of cotton fields through soil moisture sensors as the basis for control decision,combines expert experience to develop fuzzy control rules,designs a Fuzzy-PID controller,models and simu-lates the system in Simulink to simulate and analyse the Fuzzy-PID control method and the conventional PID control method.As shown by the simulation curves,the steady-state time of the proposed Fuzzy-PID control is reduced by about 7.3 s and the overshoot is reduced by 5.65%compared to the conventional PID controller.The test results show that the fuzzy-PID control method has better adjustment accuracy and steady-state performance,which can adjust the soil moisture in time for timely and appropriate irrigation,improve the irrigation accuracy of the system to a certain ex-tent,and can meet the irrigation demand of cotton in large fields.关键词
