This paper addresses the problem of attitude control of flexible spacecraft. Considering the nonlinear system under external disturbance and model uncertainty, an attitude controller based on Fully Actuated System (FAS) theory and Sinusoidal angular acceleration attitude path can be designed to achieve the attitude maneuver with minimal residual vibration. Compared to traditional controllers, FAS is often more immune to the nonlinear factors and its control law is easier to design. FAS compound with Extended disturbance observer is designed to achieve the desired linear system when compensating for the lumped disturbance and adverse nonlinearity. Moreover, the planned smooth path can suppress the flexible vibration to great extent. Simulations show that the proposed method is tolerant to the external disturbance. And it can make the modal response superior with fast convergence and small oscillation which means our algorithm can achieve quality dynamic character in a short time. This explores the application of flexible spacecraft control of FAS.
