This paper presents a barrier-based event-triggered orbital control scheme using intermittent controlled thrusts to confine a spacecraft within a narrow orbital radius around an asteroid. This ensures spacecraft safety and enables normal operation of on-board detection devices. The proposed method allows sufficient time gap between control impulses, enhancing the responsiveness of the global monitoring and decision system. Additionally, an adaptive attitude controller is designed to stabilize the spacecraft’s orientation with respect to the Sun, contributing to orbital motion stability. Numerical simulations validate the reliable performance and robustness of the proposed control strategy.
