Adaptive self-powered active vibration control to cable structures

Nonlinear resonant responses of suspended cables with a longitudinal time-delayed feedback control

“…2 obtained by the amplitudefrequency response Eqs. (24)(25), it can be observed that the peak response value varies periodically with the increase of the time delay. Additionally, the relationship curve between the external excitation and the response amplitude, as shown in Fig.…”

“…Additionally, one of the most effective and widely used countermeasures is the installation of mechanical devices, such as dampers, near the anchor end of the cables to increase structural damping and achieve vibration reduction. Passive dampers have been widely used in cable-stayed bridges, and early research on cable vibration control focused mainly on the damping performance of passive dampers, such as eddy current dampers [11,12], viscoelastic dampel [13],nonlinear viscous fluid dampers [14], positive or negative stiflness damnper [15,16], MR dampers [17,18],high-damping rubber (HDR) dampers [19], tuned inerter damper [20,21], nonlinear energy sink [22], magnetic negative stiffness eddycurrent inertial mass damper (MNS-ECIMD) [23,24] etc.…”

Active control strategy for low frequency vibration of space flexible cables based on improved sliding mode controller

“…14 Li et al adopted linear quadratic Gaussian controller (LQG) with self-powered capability to obtain the optimal active control force and demonstrated its effectiveness through simulation. 15 To sum up, most of the vibration control methods of flexible cable are optimal controllers and their improvements, which still have limited vibration suppression effect in the space environment with high uncertainty. Therefore, an improved sliding mode controller (SMC) is employed to restrain the low frequency vibration of flexible cable in this paper.…”
