Cluster spacecraft orbit defense control method, device and equipment based on APF

The invention relates to a cluster spacecraft orbit defense control method, device and equipment based on an APF. A spacecraft cluster attack and defense confrontation model is constructed; based on the spacecraft cluster attack and defense confrontation model, constructing a spacecraft cluster defense graph according to a graph theory, constructing an edge generation strategy based on the spacecraft cluster defense graph, and calculating a defense evaluation coefficient; then allocating a threat target to each guard spacecraft, and determining a defense strategy adopted when each guard spacecraft intercepts the threat target according to the defense evaluation coefficient; and generating a control law of the guarded spacecraft according to the conservative defense strategy, or generating the control law of the guarded spacecraft according to the aggressive defense strategy. According to the method provided by the invention, a spacecraft cluster defense control scheme can be obtained at very low calculation c
