An overview of satellite formation control using higher order and adaptive sliding mode control techniques

This paper is an overview of various satellite formation tracking control techniques using higher order and adaptive sliding mode control. The relative motion between the leader and the follower satellites were determined using Hill´s equations. Higher order and adaptive control techniques were implemented to maintain the desired trajectory for the satellite formation in the presence of multiple perturbations. Using the relative degree approach, the tracking accuracy of the satellite formation system has been improved. The adaptive gain super-twisting sliding mode control implemented generates the continuous control function in the presence of bounded disturbances with unknown boundaries where the control gains are not overestimated. The robustness of the different control algorithms were validated using mathematical simulations.
