液压混合动力挖掘机能量再生控制研究
Research on energy recovery control of a hydraulic hybrid excavator
摘要
Abstract
Regarding present problems of high fuel consumption and poor emission standards of excavators, a new energy saving method was proposed which combined the analysis of the working characteristic of the excavator and the fluctuations of the engine output torque with the power density characteristics of an energy regeneration system. This method configured the excavator in a parallel hydraulic hybrid instead of the traditional single power source. By way of absorbing excess engine power, rotary power, and gravitational potential energy of the active arm, this method can achieve the goal of saving energy. In order to analyze the different control methods of the energy recov-ery , a torque and speed control method based on intelligent proportional-integral-derivative ( PID) were designed. The simulation results show that the proposed method can improve system effectiveness and applicability. Addition-ally , this method can average energy power efficiently and can help recover system energy.关键词
