Active Vibration Control
In order to motivate the use of active vibration control, consider the future interferometric missions planned by NASA or ESA (one such a mission, called ”Terrestrial Planet Finder” aims at detecting earth-sized planets outside the solar system; other missions include the mapping of the sky with an accuracy one order better than that achieved by Hypparcos). The purpose is to use a number of sma...
متن کاملVibration Control of Structures Utilizing Architectural Walls
A study of architectural walls for energy dissipation and vibration control of buildings in seismic zones is presented. Typical architectural walls exhibit inelastic behavior; however, both the stiiness and energy dissipation capacity degrade after the walls are damaged. Integrating passive damping devices within these walls augments their energy dissipative abilities by widening the hysteresis...
متن کاملActive vibration control of a three-stage tensegrity structure
This experimental study demonstrates the efficiency of simple control strategies to damp a 3-stage tensegrity tower structure. The tower is mounted on a moving support which is excited with a limited bandwidth random signal (filtered white noise) by a shaker. Our goal is to minimize the transmissibility between base acceleration and top plate acceleration using piezoelectric displacement actuat...
متن کاملPiezoelectric Power Requirements for Active Vibration Control
This paper presents a method for predicting the power consumption of piezoelectric actuators utilized for active vibration control. Analytical developments and experimental tests show that the maximum power required to control a structure using surface-bonded piezoelectric actuators is independent of the dynamics between the piezoelectric actuator and the host structure. The results demonstrate...
متن کاملDecentralized control for multichannel active vibration isolation
This paper describes a theoretical and experimental investigation into an active four-mount vibration isolation system, in which electromagnetic actuators are installed in parallel with each of the four passive mounts placed between a three-dimensional piece of equipment and a vibrating base structure. Decentralized velocity feedback control is applied, where each actuator is operated independe...
