Abstract
The hardware in the loop (HIL) ground experiment simulator for on-orbit docking plays a very important role in some research fields. These fields include the research on spacecraft docking/berthing, the testing of docking/berthing mechanism, the problems reappearing of docking/berthing maneuvers and so on. This paper presents a new idea of the ground experiment simulation for on-orbit docking. The dynamic model for spacecraft docking for the HIL simulator is established. At last, the mechanical system of a virtual ground experiment simulator for on-orbit docking is established with SimMechanics block-set. The controller of the system is also established with Matlab/Simulink. Lag compensation is used to ensure the close loop performance. The result of simulation with virtual simulator shows that the above dynamic model for spacecraft docking is correct and the idea of the HIL ground experiment simulator for on-orbit docking is feasible.
