| 摘要: |
| 【目的】提高卷盘式喷灌机的灌溉性能。【方法】基于模糊控制理论实现对卷盘式喷灌机灌溉系统的智能控制，以土壤湿度偏差和土壤湿度偏差变化率作为系统的输入变量，以桁架车牵引速度作为系统输出变量，通过对系统输入变量进行模糊处理，运用模糊推理运算，获得桁架车牵引速度的模糊值，最后将模糊结果清晰化处理，得到桁架车牵引速度的真实值，并通过电机驱动实现喷灌机桁架车的行进。【结果】当土壤湿度偏差和土壤湿度偏差变化率较大时，喷灌机桁架车牵引速度较慢，可增加灌水量；当土壤湿度偏差和土壤湿度偏差变化率较小时，喷灌机桁架车牵引速度较快，可减少灌水量。【结论】针对不同的土壤湿度和土壤湿度偏差变化率，系统可以改变喷灌机桁架车牵引速度，进而改变灌水量，以达到对田间作物进行精准灌溉的目的。 |

| Abstract: |
| 【Objective】Improving the performance of irrigation systems is critical to improving their operation and water use efficiency. The aim of this paper is to present a new control method. 【Method】The intelligent control was based on the hose-reel irrigators system. It was realized by the fuzzy control theory and method, with soil moisture deviation and its temporal change taken as the input variables and the sprayer cart traction speed as the output. Fuzzy value of the traction speed was obtained by fuzzy-processing the two input-variables. It then underwent a clear-processing to obtain the real traction speed for operating the irrigation system by passing it to the driving motor. 【Result】When soil moisture deviation and its temporal change were large, the traction speed of the sprayer cart was slow in order to increase the irrigation amount. In contrast, decrease in soil moisture deviation and its temporal change accelerated the traction speed of the sprayer cart to reduce the irrigation intensity.【Conclusion】 Based on soil moisture deviation and its temporal change, the proposed control system can change the traction speed of the hose-reel irrigators to adjust irrigation intensity, achieving precision irrigation. |
