Abstract
for multiple spacecraft with actuator and angular velocity constraints using vector measurements directly. First, the novel vector measurements-based cooperative attitude synchronization control scheme is presented by using barrier Lyapunov function. Especially, the proposed control algorithm is proven to be robust to time delays in the directed communication links, and the actuator and angular velocity constraints are satisfied simultaneously. Second, further analysis of the initial condition is performed to preclude the undesired equilibrium. It indicates that at least 2 orthogonal inertial vectors are required. Third, the fully distributed attitude synchronization control strategy with adaptive gains is developed. Moreover, the control algorithm is implemented without any global information of the graph. This affords a new approach to optimize the control performance. Finally, simulation results demonstrate the effectiveness and performance of the proposed control schemes.
