Description

technical field [0001] The invention relates to a semi-physical simulation system for spacecraft control. Background technique [0002] The semi-physical simulation of spacecraft control system is a unique simulation method in the process of developing spacecraft. It uses the air-bearing turntable as a motion simulator and combines some real objects to build a semi-physical simulation environment for simulation verification of control system schemes and algorithms. The air-floating turntable uses compressed air to form an air film between the air-floating bearing and the bearing seat to make the table float in the air, so as to realize the approximately frictionless relative rotation between the air-floating turntable table and the table body, so as to simulate the spacecraft in outer space. A mechanical environment in which the disturbance moment is small. On the ground, the rotation of the air bearing turntable can be used to simulate the attitude motion of the rigid body...
