At present, with the development of world economic compression, the cost of energy has grown dramatically. Pollution and global warming have become enormously weighty problems. Many researchers are focused to reduce energy consumption and emission with the rising demand of energy saving and environmental protection in the world range. So hybrid system is one of the better solution. As a result, this paper predominantly investigates the energy recuperation system for hybrid excavator. A novel energy recuperation system is proposed and verified through simulation results which is done in the AMESim software and also competed with conventional system. In this system, a power storage component, electrical battery, is combined with a hybrid actuator using an electric motor and an electrical generator as energy convention component. In cementation, a controlling strategy which is used to control the hybrid excavator to emulate mandates conferred by a driver and to optimize the energy saving procedure of the generator and battery, is also proposed. The measures to improve the energy recuperation efficiency of the proposed system are presented. A series of simulation is performed to clarify the performance and efficiency with respect to conventional one. All parameters are taken from the real system.
