摘要：
This study deals with finite-time output feedback attitude stabilisation problem for rigid spacecraft systems subject to input constraints. First, a continuous saturated state feedback controller is proposed based on the homogeneous method, after which can guarantee the closed-loop system is global finite-time stable. Then, a switched saturated output feedback controller is developed under a state observer, after which can guarantee the closed-loop system is semi-global finite-time stable. Simulation results are given to demonstrate the effectiveness of the proposed method.
