| 摘 要： | 为了降低挖掘机能耗,提高动力系统的效率,采用了混联式控制策略。由发动机、ISG电动机组成新的动力源,由超级电容供电的回转电动机取代传统的液压马达,构成了挖掘机的回转系统,并采用了超级电容作为储能元件。建立了ISG电动机和回转电动机的控制策略,对回转电动机同时给出了转矩控制和转速控制两种控制算法,由于ISG电动机与发动机直联,因此,着重研究其转速控制算法。结合试验数据分析得出,采用混联式控制策略不仅优化了动力系统的资源配置,回收了制动能量,达到了节能减排的目的,而且实际工作效果达到甚至超过了传统挖掘机。

| Abstract: | In order to reduce the energy consumption and enhance the power system efficiency of the excavator,parallel-series control strategy is adopted.The new power source is composed of an engine and an ISG motor,and the swing motor whose power is supplied by super capacitor instead of the traditional hydraulic motor,thus the rotary system of the excavator is constituted.Meanwhile,the super capacitor serves as energy-storage components.In addition,the control strategy of the ISG motor and the swing motor are estab... |
