摘要

In this paper, leader–follower formation and reconfiguration problems based on the periodic orbits of thennonlinear relative dynamics along a circular orbit are considered. First, initial conditions of coplanar andnnoncoplanar relative orbits are characterized by the initial true anomaly, mean motion, semimajor axis, eccentricity,nand inclination angle of the follower’s inertial orbit. Based on the property of null controllability with vanishingnenergy of the Hill–Clohessy–Wiltshire equations, Ln1 suboptimal feedback controllers are designed via the linearnquadratic regulator theory. Simulation results for three examples are given. A comparison with the reconfigurationnproblem based on the periodic orbits of the Hill–Clohessy–Wiltshire equations shows that replacement by nonlinearnperiodic orbits does not increase the Ln1-norm of the feedback control.
