Abstract: To achieve precise spacecraft Eulerian attitude angle tracking control, adaptive controllers based on full-form dynamic linearization (FFDL) techniques are proposed. The open-loop system is approximated by a second-order nonlinear uncertain system, which is further transformed… read more here.

DOI: 10.1109/tgrs.2022.3226221
Abstract: Combined with terrain observation by progressive scans (TOPS) synthetic aperture radar (SAR), near-nadir SAR (N-SAR) system has great potential for surface water and ocean topography (SWOT) observation. However, one practical problem of the airborne N-SAR… read more here.

DOI: 10.1155/2020/6721301
Abstract: In this paper, a dynamic model for long-term on-orbit operation of the tethered solar power satellite (Tethered-SPS) is established. Because the Tethered-SPS is a super-large and super-flexible structure, the coupling among the orbit, attitude, and… read more here.
