Distributed vibration control with sensor networks

Distributed vibration control with sensor networks
Distributed vibration control with sensor networks
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 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 broadband vibration disturbances. The experiment results are presented for the control of the beam's vibration modes under 600 Hz. It is shown that distributed control approaches the performance of centralized control if the same control effort is applied. In addition, in comparison to centralized control, the distributed controller has the advantage that it will continue to work 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 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 broadband vibration disturbances. The experiment results are presented for the control of the beam's vibration modes under 600 Hz. It is shown that distributed control approaches the performance of centralized control if the same control effort is applied. In addition, in comparison to centralized control, the distributed controller has the advantage that it will continue to work even when some processors fail, although probably with diminished capability.
