Design and simulation of satellite formation flying position-keeping control method

Satellite formation flying position-keeping control is researched. A simulation method based on STK and Matlab for the satellites formation position-keeping control is introduced. Relative dynamical models of formation flying were derived, and Hill equations were deduced based on the circular reference orbit. Linear-quadratic regulator was adopted to perform the formation flying position-keeping control. Simulations in MATLAB Simulink show the successful use of LQR control approach for satellite formation flying position-keeping control.
