This paper addresses the issue of vibration suppression for uncertain exible riser systems. A vibration suppression method combining preset performance control, sliding mode control, and adaptive fuzzy system compensation is proposed. To guarantee both transient and steady-state performance, the original constrained control problem is transformed into an unconstrained stabilization task via a performance function. An adaptive fuzzy system with a single update law is employed to compensate for system uncertainties, and the controller's reliance solely on measurable boundary data ensures its practical implementability. Stability of the closed-loop system is rigorously proven using Lyapunov theory. Simulation results demonstrate that the proposed method outperforms benchmark controllers in terms of convergence speed, steady-state accuracy, and overshoot suppression, effectively attenuating vibration amplitudes.
