N2 - Previous research on attitude tracking control for rendezvous and docking maneuvers focuses on forcing the attitude vector to ultimately converge to the equilibrium, ignoring any consideration of when each attitude element converges relatively to the others. However, during rendezvous and docking maneuvers, it is desirable if all the attitude elements reach the target values at the same time, namely time-synchronized attitude tracking. This convergence property would significantly avoid the chattering and improve the pointing accuracy during rendezvous and docking maneuvers, resulting in a higher mission success rate. Based on the time-synchronized stability formulations, we further suitably design a time-synchronized attitude tracking control strategy. Finally, numerical simulations are conducted to present the time-synchronized attitude tracking features attained, compared with traditional control strategies; and further explorations of the merits of the time-synchronized convergence are described.
