Abstract
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 design and simulation of the planning system. Secondly, to improve system stability and robustness of strong disturbance, an autonomous attitude planning system based sliding mode control has been proposed. In addition, a constraint monitor module ensures that the attitude commands received from the attitude controllers do not violate attitude pointing constraints. Finally, simulation results demonstrate that: the methods in this paper not only meet complex attitude pointing constraints but also achieve high-precision attitude maneuver in large angle maneuver under high time-varying disturbance torque, and the attitude maneuver path is smoother and feasible for implementation.
