ADVANCES AND TRENDS IN DYNAMICS AND CONTROL OF SPACECRAFTS

The research on dynamics and control of spacecrafts for the purpose of establishing effective strategies to ensure reliable operation of spacecrafts at each stage plays a prominent role in the developments of the space technology. The space technology is developing rapidly, and showing more and more diversities, in which functions and structures of the spacecrafts become more and more complicated. The appearance of large size space stations and micro-satellites, and the developments of deep space explorations have brought about multi-couplings, nonlinearities, extreme environments, and extremely high flexibilities. The research of dynamics and control of spacecrafts is developing thoroughly in several directions, including theoretical analysis, numerical simulations, and experimental simulations. In this paper, a review is given of foundamental problems and their recent developments in dynamics and control of the multi-spacecraft, the whole system, and the components of one single spacecraft. It is mainly focused on summarizing the existing methods and results of dynamic modeling, response analysis, and vibration control of spacecrafts in different application areas, and with different hierarchical structures. Moreover, some scientific problems in need of further study, and prospects for new development directions in this field are presented at the end of this paper.
