Abstract: High-frequency perturbation effects on the performance of suppressing flow-induced vibration (FIV) have been investigated based on the study of a phenomenological model of FIV. It was predicted that the nonlinear damping term in the model, describing the behavior of vortex shedding, could be increased via active perturbation in a frequency range well-exceeding the resonant frequency of the structure. Following the direction, a multi-high-frequency perturbation controller is proposed with a feedback closed-loop system, which has achieved the best experimental performance on the vibration control. Aside from the performance comparison between the multi-high-frequency controller and traditional control methods for FIV, detailed experiment has also been carried out to study the effects of some key parameters of the proposed controller, which is composed of a low-frequency active resonator and a hard limiter. Finally, robustness study on the multi-high-frequency controller has also been carried out subject to various flow conditions.
