A single-link flexible manipulator tracking control method relates to a manipulator tracking control method. The present invention is a single-link flexible manipulator trajectory tracking control method under asymmetric time-varying full-state constraints. The dynamic model of the single-link flexible manipulator system controlled by a DC motor is used. By selecting appropriate states and making appropriate constraints on unknown bounded disturbances and tracking trajectories, in the design of an actual controller, the backstepping method is applied to the design of an adaptive fuzzy actual controller. In order to prevent the constraint from crossing the bounds, the present invention also introduces a new tan-type asymmetric time-varying hindered Lyapunov function in each step of the backstepping method design, designs corresponding control laws and adaptive laws, and ensures that no matter what the initial conditions are, a final uniformly bounded tracking control effect is achieved, and the asymmetric time-varying constraints can be achieved after a finite time.
