Study on Model Predictive Control for Robustness in Flyby mission of DESTINY+

Abstract

DESTINY+ is a flyby space mission for the asteroid named Phaethon and will be launched in 2022. Camera system in Flyby space mission has been conventionally controlled by a PD controller. However, PD controller cannot generally consider constraints. A flyby mission requires a robust control for constraints in traversing at high-speed. This paper proposes a control scheme based on Model predictive Control for a flyby mission with robustness for constraints of input and angular velocity. The simulation study shows that Model predictive Control is effective for robustness in a flyby mission.
