Abstract:

For certain space tasks which need to keep the formation during the maneuvers, the problem of three satellites formation control is solved using virtual structure. A virtual structure frame is presented. Three satellites are treated as a virtual rigid body during the maneuvers. The dynamics and kinematics controllers are designed. Dynamics controller with formation feedback realizes the control of formation velocity. An attitude sliding mode controller is presented with external interference. System stability is proved using the Lyapunov stability theorem and a numerical simulation is performed to verify the effectiveness of the method.
