WebJul 1, 2024 · Firstly, multiple small satellites are divided into leader layer and follower layer, and a hierarchical control strategy combining formation flying and satellite cluster is investigated. Secondly, the synchronous control of the leader layer with various spatial disturbances and input constraints is achieved by using FTCESO and NFTSMC. WebAbstract: In this paper, a novel approach to the tracking control problem of the satellite proximity operations between a leader and a follower satellite is presented. First, the Lagrange-like model of the satellite relative motion is derived by using proper operators which introduced in dual quaternion context.
WebLeader Satellite Follower Satellite Fig. 1 Geometry of orbit motion of leader and follower satellites Assume that the leader and follower satellites are point masses to derive the governing equations of motion. The orbital motion of the leader satellite is defined by a radial distance rc from the center of the Earth and a true anomaly θ. WebThe proposed model consists of a leader satellite which is assumed to orbit the Earth in a circular planar trajectory and a follower satellite that moves relative to the leader satellite in a desired configuration. It is also supposed that the leader satellite is separately controlled to follow a predesignated Keplerian circular orbit
