Abstract
Spacecraft attitude maneuver control in the presence of external constraint was investigated in this paper. First, the desired attitude and the forbidden attitude were represented by a quaternion, with the corresponding Euler rotation angles describing the distance of various attitudes. Second, the problem of goals nonreachable with obstacles nearby was described when using potential field methods for spacecraft attitude maneuver. To deal with the potential risk, an improved repulsive potential function was proposed by taking the attitude deviation between the spacecraft attitude and desired attitude, which ensures that the goal attitude is the global minimum of the total potential. In addition, an autonomous attitude maneuver controller was obtained by means of backstepping. Simulation results show that the proposed method is effective.
