This paper present a new method for the integration of the HIL simulation system for on-orbit docking. First, the problems, such as stability, in the integration of the HIL simulation system arc discussed. The HIL simulation tasks are discussed based on the analysis of the characteristics of the docking mechanism. A new idea and procedural to integrate the HIL simulation system is presented. The two-degree-of-freedom control structure is defined as a practical control structure for the HIL simulation system based on the analysis of the single degree-of-freedom (DOF) model of HIL simulation for on-orbit docking. The pre-filter of the two-degree-of-freedom control structure can be defined with several procedurals, for an example, QFT. By increasing the hydraulic spring rate, the sensitivity of the electro-hydraulic system to payload stiffness is reduced. The simulation results on single DOF case demonstrated that the ideas and the procedural for the HIL simulation system integration are feasible and practical.
