TV93; [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.
