Aiming at the spatial static configuration design of heterogeneous multi-satellite electromagnetic formation,a numerical calculation method using accurate electromagnetic force models is proposed to decrease the error caused by the far-field electromagnetic force model in the traditional method.Considering that there are many parameters to be optimized in the static configuration design,a set of necessary conditions for the mass distribution and spatial arrangement of the satellite formation can be derived based on the orbital relative motion equations and the internal electromagnetic force characteristics.A parameter-reducing tetrahedral configuration design method is proposed,and a nonlinear correction is applied to the static configuration solution based on the accurate electromagnetic force model.To solve the closed-loop control problem of the formation,a sliding mode controller with perturbation feedforward is designed,and the precision of magnetic dipole assignment is improved using the exact electromagnetic force model.Simulation results show that the designed tetrahedral configuration can satisfy the equilibrium of forces and moments,and the correction method based on the exact electromagnetic force model improves the precision of configuration design and control.
