Cooperative guidance method for flexible attachment of small celestial body

The invention discloses a small celestial body flexible attachment cooperative guidance method, and belongs to the technical field of deep space exploration. According to the method, the mass of the flexible detector is equally distributed on rigid modules, the rigid modules are regarded as mass accumulation areas which are relatively independent and restrained by flexible connection, and physical connection between the rigid modules is modeled as the action of elastic force and damping force by using a spring damping model. The overall attitude of the flexible detector is reflected by the relative height difference of the mass accumulation areas, a relative height difference index is established to measure the stability of the attitude, on the basis, initial and final state constraints of the mass accumulation areas are considered, a consistency protocol of the multiple mass accumulation areas is generated, and a flexible attachment cooperative guidance law in an analysis form is established accordingly.
