| 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.

| Abstract: | In order to save energy consumption of hydraulic excavators,a power-sensitive energy-saving 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-integral-differential 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. |
