Multi-slide-mode-control for fly-around in automatic rendezvous and docking

Fly-around is an important phase in automatic rendezvous and docking (AR&D). The energy expenditure is important indices of fly-around. Multi-slide-mode-control (MSMC) is developed from sliding mode control and its advantage is energy efficient. Based on MSMC, the fly-around trajectory is designed as great circle and fold-line respectively. The simulations show MSMC has good performance in fly-around of AR&D.
