摘　　要：针对柴油机驱动液压钻机在工作过程中存在的大量能量损失的问题,将发动机、变量泵及负载作为一个动态系统来研究其节能问题,分析了该系统各环节的匹配原理和方法.提出了一种新的电子节能控制方案,该方案利用模糊控制原理,结合PID控制策略,绕过对钻机复杂系统的建模问题,根据外负载的变化动态调整泵的流量,实现节能的目的.在控制系统性能试验中,通过电控溢流阀给变量泵加载来模拟钻机实际工作过程.实验结果表明,采用本文的控制策略,控制系统性能稳定,达到了设计要求.Aiming at the energy loss problem of hydraulic drilling machine driven by diesel engine, its engine, variable displacement pump and the load are considered as a whole dynamic system to study the energy saving problem. The matching principle and method of each tache in this system are analyzed. A new electric energy saving control precept is proposed. In order to avoid modeling for the complex drilling machine system, the precept uses the fuzzy theory combining PID control strategy, and regulates the flux of the variable pump dynamically to realize the purpose of energy saving. In the systematic performance experiment, the overflow valve is used to simulate the load of practical work process of drilling machine. The results show the strategy can fulfill the energy saving requirement, and the performances of the control system are stable.
