Abstract :
Fractionated satellite cluster needs coming together and avoiding crash with limited random initial relative motion conditions. A control law which simulates organism swarm motion is put forward. The concept of electromagnetic formation flight, the electromagnetic forces calculation model and the electromagnetic dipole strengths calculation method are introduced. Mass model of electromagnetic coils is established, which shows the relation of coils maximum electromagnetic dipole strength, mass of coils and electric ability of coils material. The motion of satellite follows three rules, which are avoiding crash, velocity homology and coming together. Three control forces according with the rules should be given to satellite individuals. The final control force is a sum of three control forces. Electromagnetic dipole strengths calculation is formulated as nonlinear optimization problem. The simulation shows the organism swarm motion simulation control law can keep fractioned satellite cluster coming together and avoiding crash. Electromagnetic forces realize the relative motion control.
