摘要: 为了解决传统液压挖掘机能耗高、排放大、调速性能差的问题，提出了一种基于双变动力源系统效率最优的排量自适应控制策略，以实现整机的流量匹配。该挖掘机由纯电机驱动，发挥了电机调速性能好、响应快、过载能力强的优点。本文介绍了其基本结构和工作原理，分析了整机的控制过程。通过搭建3种不同驱动方式的AMESim-MATLAB联合仿真模型，验证了该控制策略的可控性和节能性。研究结果表明，所提出的控制策略相比柴油机驱动和定速电机驱动，分别节约成本约64%和33%。
Abstract: To address the issues of high energy consumption, large emissions, and poor speed regulation performance in conventional hydraulic excavators, a novel control strategy based on a dual-variable power source system with optimal efficiency and displacement adaptability is proposed. This strategy aims to achieve flow matching for the entire machine. This strategy is driven by a pure electric motor, capitalizing on its advantages of excellent speed regulation performance, rapid response, and strong overload capacity. The basic structure and operating principle of the strategy are introduced, and the control process is analyzed. The controllability and energy-saving characteristics of the proposed control strategy were validated through the construction of a combined AMESim-MATLAB simulation model that incorporates three different driving modes. The research results indicate that the proposed control strategy achieves cost savings of approximately 64% compared to diesel engine drive and 33% compared to fixed-speed motor drive.
