英文摘要：

Based on the analyses of the hydraulic system of modeling based on the modularization of the hydraulic and of a robotic excavator,it proposed a method energy-saving control system. A simulation model including the hydraulic components of the excavator is built within which the parameters of the subsystem model can be d easily with the graphical user inter.face. Finally some of the simulation results of the hydraulic and control model are given. It is shown that this digital model can simulate the hydraulic and control system of the robotic excavator primely.
