Suppression of Random Vibration in Flexible Structures using a Hybrid Vibration Absorber M.H. Tso, J. Yuan, W.O. Wong Abstract A design method is proposed to suppress stationary random vibration in flexible structures using a hybrid vibration absorber (HVA). While the traditional vibration absorber can damp down the vibration mainly at the pre-tuned mode of the primary structure, active damping...

Abstract: Passive vibration control solutions are often limited to working reliably at one design point. Especially applied to lightweight structures, which tend to have unwanted vibration, active vibration control approaches can outperform passive solutions. To generate dynamic forces in a narrow frequency band, passive single-degree-of-freedom oscillators are frequently used as vibration abso...

In this paper a high order sliding manifold control approach is adopted as a technique to effectively reduce the vibrations of a metal rectangular panel. A novel theoretical result for an output feedback control law is presented to show how the singular perturbation theory can be used to tackle the problem of active vibration control. In this paper we address the problem of reducing vibration o...
