Abstract: A tube-based model predictive control strategy was proposed for geostationary satellite formation control. Based on the Clohessy-Wiltshire Hill (CWH) equations, the relative orbit motion model was constructed. By designing the uncertainty tube, the proposed robust model predictive controller can overcome the uncertainties brought by model mismatch. The simulation was carried out by Matlab/Simulink. Numerical results show that the proposed controller can maintain the satellite formation by dealing with various orbits perturbations and model uncertainties properly.
