Abstract
AbstractThis paper considers connectivity preservation and collision avoidance controller design for spacecraft formation flying with bounded actuation. A distributed controller with bounded artificial potential function and indirect couplings is proposed. It is assumed that all spacecraft can only obtain the states of their neighbors. The communication graph between the spacecraft is modeled via distance-induced proximity graph. A bounded potential function is presented to tackle connectivity preservation and collision avoidance problems. The spacecraft-proxy couplings address the actuator saturation constraints by designing a virtual proxy for each spacecraft. The inter-proxy artificial potential function fulfills the coordination of all spacecraft. Numerical simulations confirm the effectiveness of the anti-saturation distributed connectivity preservation controller.KeywordsSpacecraft formation flyingBounded actuationArtificial potential functionConnectivity preservation
