Abstract:

This paper investigates the autonomous control problem for non-cooperative targets, and proposes a multi-mode control approach based on the hybrid state machine. First, according to the task objective of fly-around and orbit safety analysis, we define six states including long-range guidance, close-range guidance, relative-position keeping, fly-around transfer, collision threat avoidance, and evacuation. Moreover, the control objective of each state is designed. Second, to achieve the coordinated transitions and control between the states, a state monitoring and management approach is developed and state transition functions designed based on the finite state machine. A novel multi-mode motion plan and adaptive finite-time control strategies are then proposed to guarantee the tracking performance according to the task objective. Finally, the proposed autonomous fly-around control approach is simulated by digital simulation software, and the simulation results show the effectiveness of the proposed approach.

Key words: autonomous fly-around control, hybrid systems, finite state machine, multi-mode control, collision threat avoidance
