| 摘 要： | 针对液压挖掘机在工作过程中存在的大量能量损失,根据泵的控制特性曲线,将发动机、变量泵、控制阀及负载作为一个动态系统来研究其节能问题。提出了一种新的电子节能模糊控制方案。此方案利用模糊控制的优点,绕过对挖掘机复杂系统模型的建立,通过模糊推理算法,根据外负载的变化动态调整泵的流量,达到节能的目的。

| Abstract: | In the light of significant energy losing during the hydraulic excavator working, a dynamic system was made up from the diesel engine,the variable pump,the control valve and the load to cut down the losing energy from a systematic approach based on the control characteristics of the system elements.An electronic fuzzy control scheme for energy saving was presented.Taking advantage of the good points of the fuzzy control adjusting the flow rate of the pump according to the variation of the external load by fuzzy inference,the energy saving of the excavator is accomplished without the help of the modelling of its whole complex system. |
