This study is concerned with the problem of composite anti‐disturbance control for attitude manoeuvre and vibration reduction in the presence of external disturbances. By employing finite‐time integral sliding manifold, a novel finite‐time integral sliding mode disturbance observer is constructed to estimate the lumped disturbances in finite time, where the lumped disturbances include external disturbances and coupling terms between system states and flexible modal. Based on the estimation values, a composite anti‐disturbance controller is proposed via backstepping method. Simulation results are employed to demonstrate the effectiveness of the proposed technique.
