Abstract

The invention relates to a flexible spacecraft ground control test platform and a test method, which relate to the field of aerospace, and solve the problem that a realistic simulated test can be performed on a ground control system difficultly by the existing flexible spacecraft ground control test platform. The test platform comprises an air flotation rotary table, a rigid main body, a flexible accessory, equipment above the rotary table and equipment under the rotary table, wherein the equipment under the rotary table comprises a ground control host, a ground database, a rotary table motion measuring device and a set of wireless communication devices; and the equipment above the rotary table comprises a sensor and an xPC main controller. The test method is implemented on the basis of the test platform. The flexible spacecraft ground control test platform and the test method lay a foundation for developing the ground control system of a flexible spacecraft.

Description

technical field [0001] The invention relates to the field of aerospace, in particular to a flexible spacecraft ground control test platform and a test method. Background technique [0002] With the development of aerospace technology, modern spacecraft often have large flexible accessories such as solar panels and antennas. There is a strong rigid-flexible coupling between the central rigid body and flexible appendages of this type of flexible spacecraft, which is difficult to describe mathematically accurately. For this type of complex spacecraft with flexible accessories, due to the particularity of its operating environment, high risk, high cost, and high precision and high complexity of the control system, it is not enough for the control system scheme to be simulated only through numerical simulation. A full semi-physical simulation test of the satellite control system must be done before going to the sky to verify the stability of the system design, modify the system ...
