英文摘要：
To solve the problem of position and attitude control of a spacecraft in the presence of parametric uncertainties and external disturbances, an adaptive sliding mode control approach is presented. The proposed approach is employed to control the position and attitude of the spacecraft in order to capture and remove large space targets by performing position and large angle maneuvers. The proposed control algorithm eliminates the requirement of uncertainty bound and is easier to implement than the traditional sliding mode control approach. The proposed controller ensures the asymptotic position and attitude tracking through Lyapunov analysis. Simulation results are presented to demonstrate the effectiveness of the proposed design method.
