摘要此研究项目中提出了一种新型液压能量再生系统并建立了相应模型。该系统是一个基于封闭回路的静液压传动装置，用液压蓄能器作为能量存储，用来恢复动能，不需要任何流体流动逆转。辅助单元的位移量减少可以增加几种液压泵/马达使用效率。根据其物理属性可以为系统建立模型。控制系统中，设计了一个自适应模糊滑模控制模块来实现二级单位的速度控制，同时我们也分析了系统的能量回收效率，并且通过仿真和实验评估了控制系统的数学模型的有效性。实验结果表明，所设计的系统是有效的，往返回收效率为22％~59％。
绪论由于燃料价格的增加和环境污染，节约能源已经变得越来越重要。节能系统基于混合动力概念轿车，卡车推土机和施工机械（即，轮式装载机，挖掘机，收割机）进行了研究，以减少能源消耗和废气排放。节能系统可分为若干类型：电，机械，使用电池的液压系统，飞轮，液压蓄能器，节能系统。这些节能系统的结构、特点和适用性在以前进行过总结和分析。由于它的高回收效率和高比功率，液压节能系统是一种非常有希望的技术。
