This chapter studies the distributed leader-follower consensus for multiple flexible spacecraft with actuator faults under an undirected tree graph. The attitudes of the networked flexible spacecraft are represented on the special orthogonal group SO(3) globally and uniquely. A fault-tolerant tracking controller is proposed to protect against the partial loss of actuator effectiveness based on sign function. Then the saturation function with an adaptive parameter is introduced to replace the sign function. Rigorous Lyapunov analyses are presented to prove the stability of the overall system. Finally, numerical simulations are conducted to verify the effectiveness of the proposed controllers.
