Abstract

The relative position and formation attitude control of a two-spacecraft utilizing coulomb forces as well as thrusters is addressed. The nonlinear control is realized through state dependent Riccati equation (SDRE) control method. To this end the equations of motion of the formation is properly manipulated to obtain a suitable form for SDRE control. The state-dependent coefficient (SDC) form is then formulated to include the non-linearities in the relative dynamics. The effectiveness of the controllers is demonstrated through simulations.
