Based on the principle of electromagnetic spacecraft, a Lagrange method was used to establish the electromagnetic spacecraft “rope system ” dynamics model.Based on the deviation linearization dynamics model, taking tangential and radial formation as an example, the formation configuration The stability of the design and the control law of the design configuration are maintained. The reconstruction motion planning problem of EMFF (electromagnetic formation flight) is transformed into a standard optimization problem, which is solved by means of Gaussian pseudospectral optimization method. A sequence control strategy is proposed, The binary star model is extended to the multi-star electromagnetic formation reconfiguration problem, which is transformed into multi-phase motion programming problem using multi-stage optimization method. The simulation results show that the dynamic modeling method and control method are feasible.
