Experiments on distributed active vibration control of a simply supported beam

Experiments on distributed active vibration control of a simply supported beam
In this paper, the application of distributed vibration control for a flexible structure is studied both analytically and experimentally. The purpose is to investigate the effectiveness of distributed vibration control strategies and to compare them with centralized and decentralized methods. A simply supported beam is chosen as the illustrative flexible structure. A distributed control architecture is designed based on a system identification model and is used to minimize vibration due to broadband disturbances. Experimental results are presented for the control of the beam's vibration modes under 600 Hz. It is shown that the distributed control architecture presented here approaches the performance of a traditional centralized controller employing the same control effort. In addition, in comparison to centralized control, the distributed controller has the advantages of scalability for application in large systems and that it will continue to perform even when some processors fail, although probably with diminished capability.

Abstract

In this paper, the application of distributed vibration control for a flexible structure is studied both analytically and experimentally. The purpose is to investigate the effectiveness of distributed vibration control strategies and to compare them with centralized and decentralized methods. A simply supported beam is chosen as the illustrative flexible structure. A distributed control architecture is designed based on a system identification model and is used to minimize vibration due to broadband disturbances. Experimental results are presented for the control of the beam's vibration modes under 600 Hz. It is shown that the distributed control architecture presented here approaches the performance of a traditional centralized controller employing the same control effort. In addition, in comparison to centralized control, the distributed controller has the advantages of scalability for application in large systems and that it will continue to perform even when some processors fail, although probably with diminished capability.
