During the deep space exploration missions a lot of attitude maneuvers need to be completed for the change of different attitude. Meanwhile, in the course of the explorer attitude maneuver there are many attitude pointing constraints due to the diversity of space tasks. Firstly, attitude kinematic and dynamic equations based on quaternion are established in this paper, which laid the foundation for...
For the attitude maneuver of spacecraft under pointing constraints, an algorithm based on navigation function and backstepping method is proposed in this paper. By proper construction of navigation function for the constraint attitude control problem, the end of the direction vector of sensor can move in free work space, which is intuitively on the unit spherical surface, and almost globally converges...
During the asteroid exploration mission, attitude maneuver is subjected to various constraints, such as geometric constraints, dynamic constraints etc. To accomplish rapid maneuver from the initial attitude to the target attitude under the complex system constraints, autonomous attitude maneuver planning problem should be considered. This article fully considers the constraints in deep space environment,...
In deep space exploration, unknown environment require the real-time controlling on an explorer, however the time delay of communication and signal blocking by stars make it impossible for the explorer to achieve real-time controlling. In order to solve the real-time attitude controlling problem for deep space explorers, the characteristics of complex system structure, coupling constraints, and parallel...
