This article investigates the attitude synchronization problem of spacecraft formations. A class of continuous sliding mode control schemes with finite-time convergent property is developed. The control laws are designed by the utilization of behavior-based control approach. An improved version of terminal sliding mode is applied in both the reaching phase and the sliding phase of the control system. In the presence of external disturbances, the proposed control strategies are able to overcome the unexpected phenomenon and can steer the spacecraft formation to a dynamic reference attitude state coordinately subject to arbitrary communication topologies. Numerical simulations are provided to validate the theoretical analysis.
