Spaceborne antenna deployment control system

The invention relates to a spaceborne antenna unfolding control system, which at least comprises a mechanical power output system, a rotation angle measuring component, a first output component and a second output component, and takes the extension direction of a virtual rotation axis of two plane components rotating relative to each other as a first direction, the mechanical power output system is provided with a first bearing surface and a second bearing surface, and the two end surfaces of the mechanical power output system are connected to different plane components through first output components correspondingly. The included angle formed between the two plane components can be increased or decreased according to the mode that the relative position relation between the first bearing face and the second bearing face is changed. The rotation angle measuring part is connected to different planar members through the second output part, and the rotation angle measuring part and the mechanical power output system are connected in the mode that the rotation angle measuring part and the mechanical power output system are located on the two sides of the planar members in the first direction respectively and can conduct information interaction with each other.
