چکیده

This work is devoted to design, implement and validate an active mass damper (AMD) for vibration mitigation in slender structures. The control law, defined by means of genetic algorithm optimization, deployed on a low-cost processor (NI myRIO-1900), experimentally validated 13.5-m lively timber footbridge. As known, problems arising from human-induced vibrations slender, lightweight low-damped structures usually require the installation mechanical devices, such as AMD, order be mitigated. kind device tends reduce movement structure, which can potentially large when it subjected dynamic loads whose main components match its natural frequencies. In those conditions, AMD sought improve comfort fulfil serviceability conditions pedestrian use according some design guides. After identification actuator, procedure consisted experimental characterization modal properties structure (natural frequencies damping ratios). Once equivalent state space system obtained, law developed, based feedback, was controller. Finally, adjustments (filters, gains, etc.) were implemented validation test carried out. performance has been evaluated using different metrics, both frequency time domain, under scenarios, including transits demonstrate feasibility, robustness good proposed system. strengths presented reside in: (1) evolutionary algorithms optimize estimator gain feedback that commands further tested analyzed fitness functions related domains (2) implementation processor, represents significant advantage comes this real structure.

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)...

Optimization of Tuned Mass Damper Parameters Using Evolutionary Operation Algorithm

Optimum parameters of Tuned Mass Dampers (TMD) are determined in this paper to minimize dynamic response of a multi-storied building system. The response of the structural system is simulated under lateral excitation. To optimize dynamic parameters of the TMD system for minimum top deflection of the structure, a numerical global optimization algorithm called Evolutionary Operation (EVOP) is use...
