【摘要】：设计了一种基于模糊控制和电磁比例阀的自动灌溉系统,并进行了MATLAB仿真。该自动灌溉系统由传感器、信号传输—接收装置、控制单元和执行元件组成。根据设定的所需土壤湿度,采集各传感器信号,用PLC做模糊控制运算,输出控制信号到执行元件,控制电磁阀的开度,从而控制喷灌流量的大小。该方法设计了模糊控制输入模拟量和阀开度的隶属度函数,仿真结果显示满足预期的控制要求。最后,对系统的实际应用作了相关设计。
[Abstract]:An automatic irrigation system based on fuzzy control and electromagnetic proportional valve is designed and simulated by MATLAB. According to the required soil moisture, each sensor signal is collected, the fuzzy control operation is done with PLC, the control signal is output to the executive element, and the opening degree of solenoid valve is controlled. In order to control the size of sprinkler irrigation flow, the membership function of fuzzy control input analog and valve opening is designed, and the simulation results show that the expected control requirements are satisfied. Finally, the practical application of the system is designed.
