摘要

摘要: 为充分发挥工程车辆用发动机及液压系统的工作性能,并同时提高其在动态条件下的功率传递效率,对发动机-变量泵-变量马达(三变量)组成的串联型液压驱动系统控制策略进行研究.对驱动系统各个部分进行参数匹配,确定各环节的额定计算工况; 提出自适应分层控制策略,以系统效率最大化为目标,主动调节发动机、变量泵以及变量马达的工作点,主动适应负载功率需求.在MATLAB/Simulink软件中对系统进行后向建模,仿真结果表明,所提出的控制策略能够有效地保证系统高效率的功率传递,通过优化发动机工作点降低油耗.

Abstract: To give full play to the working performance of engine and hydraulic system used for engineering vehicle and simultaneously increase its power transfer efficiency under dynamic working conditions, the control strategy for engine-variable pump-variable motor (three-variable) series hydraulic drive system was researched. The parameters of various components in this system were analyzed and matched to determine the rated working conditions of each link. An adaptive hierarchical control strategy was adopted, and then the operating points of engine, variable pump and variable motor can be adjusted actively to match the power of engine and load relying on the maximization of system efficiency for a given working condition. Then the backward-facing simulation model of this system was established in MATLAB/Simulink. The simulation results show that the above control strategy can effectively ensure the high power transfer efficiency and the engine working conditions can be optimized to reduce engine oil consumption.
