Optimal guidance and control of spacecraft swarms in planetary and asteroid orbits
Abstract/Contents
- Abstract
- Spacecraft swarms are the future of space missions because of their inherent redundancy, cost efficiency, and ability to achieve previously unattainable science objectives. To date the usage of swarms has been limited by a lack of available guidance and control algorithms that are compatible with these small spacecraft qualities. This dissertation introduces novel delta-v efficient guidance and control algorithms to enable swarming missions for both planetary and asteroid orbits. Specifically, this dissertation develops new relative motion models of spacecraft in asteroid orbits and presents delta-v optimal swarm guidance and control for two nominal swarm operations: 1) swarm reconfiguration, the adjustment of the swarm relative geometry, and 2) swarm keeping, the maintenance of the swarm relative motion geometry. For guidance, convex programs are formulated that minimize swarm delta-v usage during keeping and reconfiguration phases. The programs are analyzed in depth for different dynamic environments and ROE reconfigurations to produce analytical solutions or reduce computational effort for use either on ground or on orbit. For control, this dissertation presents novel swarm reconfiguration and keeping algorithms to enable swarming of asteroids and provide safe, delta-v efficient functioning. For swarm reconfiguration control, this thesis presents two novel controllers, one for near-circular and one for eccentric orbits, based on Lyapunov theory. For keeping, this thesis develops a keeping control algorithm applicable to asteroid orbits that considers the unknown asteroid dynamic field for the first time in literature. The advancements presented in this thesis are validated extensively through various example missions with a focus on the Starling-1 mission and the ANS mission concept. The algorithms and advancements developed here demonstrate significant delta-v savings and safe operation over the mission lifetime. As such, these advances enable the usage of spacecraft swarms to increase both knowledge gained from space missions and mankind's presence in space.
