摘　　要：针对传统丘陵山地农业灌溉通常采用人工控制电磁阀进行灌溉所出现的水资源浪费、人工成本高等问题,设计了一套基于模糊控制和PID控制的丘陵山地农作物自动灌溉控制系统,将PID控制的稳定性和模糊控制的适应性相结合来控制灌溉时长。通过Simulink搭建的丘陵山地灌溉系统,分别用常规PID和模糊PID来控制该系统进行仿真实验。结果表明:模糊PID控制下的系统相比于常规PID控制,超调量和调节时间都明显降低,具有更高的稳定性、适应性和调节性能,可以用于丘陵山地农业自动灌溉系统中。In view of the traditional agricultural irrigation in hills and mountains,which usually uses artificial control solenoid valve for irrigation,the problems of water waste and high labor cost has come into being.A set of automatic irrigation control system based on fuzzy control and PID control is designed.The stability of PID control and adaptability of fuzzy control are combined to control irrigation time.The irrigation system of hills and mountains built by Simulink is controlled by conventional PID and fuzzy PID respectively.The simulation experiments show that compared with the conventional PID control,the fuzzy PID control system has significantly reduced overshoot and adjustment time,and has higher stability,adaptability and adjustment performance.It can be used in the automatic irrigation system of hilly and mountainous agriculture.
