Partial state based attitude control and momentum management for spacecraft

摘要

In the paper, we address the attitude control and momentum management problem of the spacecraft with patrial sate information. A three-axis coupled nonlinear dynamics subject to various uncertainties is investigated, and the ADRC technique is applied. The proposed control scheme synthesizes a linear quadric regulator controller, a MIMO-type extended state observer and a novel compensator, which only counteracts the non-accumulated uncertainty of the system. Stability analysis is thoroughly carried out Numerical example validates the effectiveness of the proposed approach.
