Rigid-Flexible Coupled Dynamic and Control for Thermally Induced Vibration and Attitude Motion of a Spacecraft with Hoop-Truss Antenna

Abstract: As space exploration activities are developing rapidly, spacecraft with large antennas have gained wide acceptance in providing reliable telecommunications and astrophysical observations. In this paper, the dynamic responses and control strategy for a spacecraft with a large hoop-truss antenna under solar flux shock are studied. According to the momentum and angular momentum principle, the rigid-flexible coupled rotational dynamic equation and the translational dynamic equation of the system are established, w… Show more

“…Azimi and Joubaneh [23] studied the dynamic modeling and vibration control of spacecraft with a flexible appendage embedded with piezoelectric patches; the strain rate feedback control law is utilized to suppress the vibration of the flexible appendage. Liu et al [24] studied the dynamic responses and control strategy for a spacecraft with a large hoop-truss antenna under solar flux shock; the thermal flux is treated as an external excitation in this work, but the influence of thermal stress on the dynamic properties of the antenna structure is not considered. From the literature review, we can see that, in previous works, most investigations focused on spacecraft with regular-shaped flexible appendages, such as a beam, plate, or shell.…”
