“…The installation power of the engine is reduced by 25%, and the speed of the boom can be increased by 80%. N S Kurochkin et al [8] proposed a method to select the coefficient optimality criterion on the control optimization method, in order to control the intersection point of the allowable range of object coordinates. By using this method, the maximum dynamic moment can be significantly reduced, and the transient time can be reduced, so as to improve the manipulative performance of the boom.…”

In order to solve the problem that the operational characteristics of the boom after the boom potential energy recovery system(BPERS) is adopted in the hybrid hydraulic excavator are reduced, aiming at the electrical BPERS, A compound control strategy is proposed to control the speed of the hydraulic cylinder of the boom by the throttle valve without pressure compensator and to control the target torque of the hydraulic motor - generator unit(HMGU) by the pressure difference between the inlet and outlet of the throttle valve. Then establishing the mathematical model of the system and analyzing the frequency response of the system. Finally, the AMESim software is used to simulate and analyze the BPERS. The results show that the control method of the BPERS is feasible. The method can not only realize the recovery of the boom potential energy, but also improve the operation characteristics of the excavator boom system.
