摘要
为了减少液压挖掘机的燃油消耗,在分析传统转速传感节能控制策略的基础上,提出了一种新的功率敏感节能控制策略.应用基于T-S模型的模糊PID控制算法,对发动机变量泵的功率匹配进行控制,并根据仿人工智能的思想对模糊规则进行了优化,提高了控制系统的动态特性.两种节能控制策略的对比试验表明,采用功率敏感节能控制策略之后,节省燃油20%以上.
In order to save energy consumption of hydraulic excavators, a power-sensltive energysaving control system is proposed, after an analysis on the traditional speed-sensitive energy-saving control strategy. Pump-engine power matching is realized using the T-S fuzzy proportion-integraldifferential control algorithm, and the fuzzy rules are optimized according to artificial intelligent simulation. This improves the dynamic response characteristics of the control system. Experimental results of the two energy-saving control systems showed that the power-sensitive energy-saving control strategy can save more than 20 percent in energy consumption compared with the speed-sensitive energy-saving control.
