After analyzing the typical working conditions of boom energy regeneration system,a energy regeneration system based on a motor and a generator was proposed.Then,a mathematical model was constructed.The effects and improvements of system dynamic response were analyzed. The united simulation of the energy regeneration system was carried out with AMESim and MAT-LAB/simulink and the influences of the pipe length,the time constant of the generator and the rotary inertia of the motor and the generator on the control performance was brought forward.Finally,a test rig was constructed.
