Position and Attitude Feedback Controller of a Planar Satellite with Two Thrusters
Takashi Matsuno,Shinji Hokamoto 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
This paper proposes a feedback control method for the in-plane motion of a satellite equipped with two thrusters, whose force directions are fixed to the satellite. The satellite’s equations of motion have second-order nonho-lonomic constraints. This paper utilizes an invariant manifold and develops a feedback controller based on the Lyapu-nov’s second method. The developed controller can control the satellite’s state composed of six components for the po-sition and attitude angle by two thruster systems. Furthermore, the controller has robustness for the system’s modeling errors. Some simulations results are shown to demonstrate the effectiveness of the developed controller.
