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)...

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

The effect of time delay on control stability of an electromagnetic active tuned mass damper for vibration control

The aim of this paper is to investigate the effect of time delays on the stability of a zero-placement position and velocity feedback law for a vibratory system comprising harmonic excitation equipped with an electromagnetic active tuned mass damper (ATMD). The purpose of the active control is broadening the vibration attenuation envelope of a primary mass to a higher frequency region identifie...

Fuzzy Control of Seismic Structure with an Active Mass Damper

Fuzzy theory is highly promising for active structural control. The advantage of fuzzy controllers over classical controllers is the limited number of measured structural responses used to implement the control rules and its intrinsic robustness. In this paper, Fuzzy rules were generated firstly by learning from sample data obtained from the performance of the system under optimal control algor...

Characteristics of Active Forces in Structural Hybrid Mass Damper Control Systems

This paper gives the numerical analysis on characteristics of active force in HMD control systems. In order to quantitatively evaluates the direction characteristics of active force with respect to the relative displacement or velocity of mass piece, a set of five performance indexes are defined, and also the ratios of either peak value or RMS value of active force to inertia force. This set of...
