Transverse Vibration Control for Cable Stayed Bridge Under Construction Using Active Mass Damper

Active Vibration Control of a Bridge Tower Structure Using Filtered Lq Control Technique

A lumped modeling method and a therein based simple robust control design are proposed in this paper for controlling the multiple vibration modes of a bridge tower structure under construction. The method is specified by a physical state-space suboptimal controller, designed upon a lumped model, combined with the socalled "structure filters" and the software filters for preventing spillover of ...

H∞ robust control design of active structural vibration suppression using an active mass damper

A mathematical model of any real system is always just an approximation of the true, physical reality of the system dynamics. There are always uncertainties in the system modeling. This paper outlines a general approach to the design of an H∞ control of an active mass damper (AMD) for vibration reduction of a building with mass and stiffness uncertainties. Linear fractional transformation (LFT)...

Vibration Control of a Power Transmission Tower with Pounding Tuned Mass Damper under Multi-Component Seismic Excitations

In this paper, the two-dimensional vibration controls of a power transmission tower with a pounding tuned mass damper (PTMD) under multi-component seismic excitations are analyzed. A three-dimensional finite element model of a practical power transmission tower is established in ABAQUS (Dassasult Simulia Company, Providence, RI, USA). The TMD (tuned mass damper) and PTMD are simulated by the fi...

Semi-active vibration isolation of a quarter car model under random road excitations using Magnetorheological damper

Semi active control systems are becoming increasingly popular because they offer reliability of passive systems combined with high performance and versatility of active control systems but with low power consumptions. As Magnetorheological (MR) fluids can produce good controllable damping force under application of magnetic field, MR damper can be used as effective element in semiactive vibrati...
