摘要

由电液执行器驱动的分散独立电液控制系统具有高效率和优良的控制性能。然而，EHA的高成本制约了系统的发展。本文全面研究了不同的EHA布局对系统运行性能和成本的影响。在此基础上，提出了一种新型的半分散独立电液控制系统，并将其应用于6吨挖掘机机械手。考虑斗土挖掘力，建立了挖掘机精确的液压-机械耦合模型，设计了四象限能量回收/存储控制策略。研究结果表明，与传统负载敏感系统相比，该系统在仿真模型下的节能率高达44.4%，在实验验证下的等效节油率约为47.02%。与传统的去中心化系统相比，该系统的成本降低了33%。

Design and energy consumption analysis of a decentralized independent electro-hydraulic control system

Decentralized independent electro-hydraulic control system driven by electro-hydraulic actuators (EHAs) has high efficiency and excellent control performance. However, the high costs of EHA restricts the development of systems. This paper conducts a comprehensive investigation of the impact of various separate EHA layouts on both the operational performance and cost of the system. Additionally, a novel semi-decentralized independent electro-hydraulic control system integrating EHAs and load-sensing actuators is proposed and applied to a 6-ton excavator’s manipulator. Considering bucket-soil digging force, an accurate hydraulic-mechanical coupling model of the excavator is established, and a control strategy for four-quadrant energy recovery/storage is designed. The findings indicate that, compared to the traditional load-sensing system, the proposed system can achieve energy-saving rates of up to 44.4 % in simulation models, and an equivalent fuel saving rate of approximately 47.02 % under experimental verification. The proposed system reduces costs by 33 % compared to conventional decentralized systems.
