摘要：目前AGV小车多采用蓄电池供电，根据规划路径实现自动行走。针对AGV小车加速时电能消耗过大和续航里程难以满足日常生产需求等问题，本文设计了一种新型电液混合动力系统，用来降低加速时的电功率消耗并有效回收制动能量，从而延长蓄电池的续航时间。基于AMESim和MATLAB/Simulink软件建立了电液混合动力系统的动力学和控制模型，对AGV小车在循环工况下的动力特性和能耗进行联合仿真。仿真结果表明，在液压动力的混合驱动下，新型电液混合动力系统不仅具有较好的动力性能，而且相比纯电动系统的能耗有所降低，对小车的续航里程改善有积极意义。

Abstract：At present, most AGVs are powered by batteries and walk automatically according to the planned path. Aiming at the problems that the AGV consumes too much power when accelerating and the endurance is difficult to meet the daily production needs, a new type of electro-hydraulic hybrid power system is designed to reduce the electric power consumption during acceleration and effectively recover the braking energy so as to extend the battery life. Based on the AMESim and MATLAB/Simulink software, the dynamics and control model of the electro-hydraulic hybrid power system is established, and the dynamic characteristics and energy consumption of the AGV under cyclic conditions are jointly simulated. The simulation results show that due to the hybrid drive of the hydraulic power, the new electro-hydraulic hybrid system not only has better power performance, but also reduces the energy consumption compared to the pure electric system, which has great significance on extending the endurance of the AGVs.
