Abstract

Recent advances in small, low cost satellite technology has generated a renewed interest in formation
flying missions. One challenging aspect of satellite formation flying missions is collision free navigation and
control. In this paper, novel robust control algorithm using Sliding Mode Control is presented for a threedimensional, high Earth orbit satellite formation scenario. The paper presents the comparison of results of three
types of Sliding Mode Controllers (SMC): the first one is a tan-hyperbolic SMC, the second one is a constant
plus proportional rate SMC and the third one is a power rate SMC. Hybrid propulsion system minimises the use
of on-board power for close formations. Artificial Potential Field method is used for collision-free path planning
of the satellites in the formation. Simulation results show that for the formation flying scenario considered in this
study, the constant plus proportional rate SMC and the power rate SMC gives better performance over the tanhyperbolic SMC. Simulation results prove that for the tetrahedron formation considered in this study, the total
control effort is less when the constant plus proportional rate controller and the power rate controller are used
compared to the tan-hyperbolic sliding mode controller. Very little formation center movement is observed for
the three SMCs.
