摘　　要：针对传统棉田节水灌溉系统灌溉精度低、运行稳定性差的问题,设计了一种基于Fuzzy-PID控制的棉田节水灌溉控制系统。系统通过土壤湿度传感器采集棉田的实时土壤湿度作为控制决策依据,结合专家经验制定模糊控制规则,设计了Fuzzy-PID控制器,并在Simulink中对系统进行建模与仿真试验,对Fuzzy-PID控制方法和常规的PID控制方法进行仿真分析。仿真曲线表明:与传统PID控制器相比,Fuzzy-PID控制的稳态时间减少了约7.3 s,超调量减少了5.65%。试验结果表明:模糊PID控制方式调节精度和稳态性能更好,可及时调整土壤湿度,进行适时、适量的灌溉,一定程度上提高了系统灌溉精度,可以满足大田棉花灌溉需求。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 systems.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 simulates 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 extent,and can meet the irrigation demand of cotton in large fields.
