The invention discloses a spacecraft cluster clustering cooperative control method based on an all-drive system theory, and belongs to the technical field of spacecraft cluster flight control. The invention aims to solve the problem that the existing multi-spacecraft grouping collaboration theory needs to meet the inter-group communication balance condition among each group of spacecrafts and is difficult to apply in a real spacecraft cluster. Comprising the following steps: establishing an attitude dynamical model based on modified Rodrigues parameters, and deforming the attitude dynamical model into a general form of an Euler-Lagrange equation; establishing a hierarchical clustering topological structure based on a plurality of virtual pilot spacecrafts at the same time; establishing an attitude error dynamic model, and designing a pseudo-linear feedback control law; designing a cooperative control law of the spacecraft cluster system by using information transmitted by the hierarchical clustering topologic
