基于PLC的模糊控制灌溉系统的研制

    Design and implementation of fuzzy control for irrigating system with PLC

    • 摘要: 该文利用模糊控制技术实现灌溉实时控制。利用MATLAB语言对其进行仿真,得到了较为合理的模糊控制算法。并将这些模糊控制算法通过以可编程控制器PLC为核心的硬件控制电路应用于实际的灌溉控制,通过实际温室育苗调试,能够较好地满足温室育苗使用要求。

       

      Abstract: A kind of real-time control irrigating system is put forward with fuzzy technology based on the characteristics of the water demand for young plant in greenhouse. And some reasonable fuzzy rules are found by computer simulation in MATLAB. Then, a hardware circuit that Programmable Logic Controller(PLC) is the control center was made, and these fuzzy rules were written in the ladder language. The hardware system was applied in real-time irrigating system for young plant in greenhouse. The debugging results show that it can meet the demands for young plant growing in greenhouse.
