The invention discloses a flexible spacecraft attitude adaptive dynamic surface control method. The method comprises the following steps: establishing a flexible spacecraft system attitude kinematics model and a dynamic model; a self-adaptive robust nonlinear attitude controller and a self-adaptive nonlinear active vibration suppression controller are designed, the robust attitude controller adopts a dynamic surface control technology, complex differential operation is avoided, unknown inertial parameters and a system disturbance upper bound are adaptively estimated by combining self-adaptive control and sliding-mode control, and the self-adaptive nonlinear active vibration suppression control is realized. System disturbance is controlled, and a vibration suppression controller performs self-adaptive processing on unknown parameters of a nonlinear suppression algorithm by utilizing self-adaptive control to realize active vibration control; and carrying out flexible spacecraft attitude adaptive dynamic surface control through the controller. The feasibility of the control scheme is proved through Lyapunov stability analysis, and the simulation result shows that the provided control method can complete high-quality attitude control and vibration suppression performance and has good adaptability.
