Adaptive Finite-Time Attitude Coordination Control for Spacecraft Formation

摘要

This paper studies the finite-time attitude coordination control for formation spacecraft systems with external disturbances. We consider two cases, namely the coordinated attitude control with actuator healthy and actuator bias faults. The adaptive sliding mode coordinated control laws are proposed and analyzed. By applying Lyapunov stability theory, it is proved that system is finite-time stable and attitude synchronization can be achieved.
