英文摘要： Attitude control system with moving-mass is becoming one preferred scheme for the next generation attitude control system of spacecrafts, because it can play an irreplaceable role with the significant advantages of the tolerance to stress and environmental adaptability and the all built-in property. With the reseach results on full actuated moving-mass attitude control system, a new integrated design framework on the underactuated moving-mass attitude control system for spacecraft is proposed in the project, which includes: 1. integrated modeling the underactuated moving-mass attitude control system with the consideration of the actuators; 2. optimizing the structural parameters of the underactuated moving-mass attitude control system with the performance indexes set based on the theory of the degree of controllability; 3. designing stabilizing and tracking controllers of the underactuated moving-mass attitude control system based on nonsmooth feedback theory. The project aims at improving the theoritical methods of structrual optimization and control design of the high-order underacturated systems,and setting up a new integrated framework on the analysis and design of the underactuated moving-mass attitude control system in order to improve the engineering realization, optimization the mass carried of the space
