摘要：A novel spatial microgravity simulation system is proposed for big and middle experimental objects with complex movement. The equipments combine machine transmission、motor drive and air-bearing to realize three-dimension spatial microgravity simulation. Level pane adopts air suspending, upright adopts motor drive, by reducer，ball screw and guide pole. Force feedback control aim gravity real timely as controller. Friction non-linearity of machine system and outside disturbance are considered. Variable Structure controller is employed to reduce disturbance and uncertainty. The experimental result shows that test equipment has light weight, convenience using and higher precision, and compensates non-linearity infection for grasping of robotic manipulator, has important engineering value to three-dimension spatial microgravity simulation.
