Adaptive attitude coordination control for spacecraft with actuator faults and external disturbances

In this paper, a spacecraft attitude adaptive coordination control scheme is proposed, which considered the external disturbances and actuator faults that are time varying and unknown. By this control method, the time-varying multiplicative and additive actuator faults are solved, and the external disturbances was compensated. The attitude tracking error by the boundary function and the error conversion function can converge to a given range. Finally, the control scheme is demonstrated to be effective by the simulation results.
