| Summary: | Flexible structure systems are known to demonstrate an intrinsic property of vibration when subjected to disturbance forces, leading to components and/or structural damage (Tokhi and Hossain, 1994). An understanding of the principles involved in the analysis of such systems is crucial so that suitable control laws for effective suppression of undesirable vibrations can be developed. Many attempts have been made in the past at devising methods of tackling the problems arising due to unwanted structural vibration or disturbance. Recently, much effort has been expended on active vibration control (AVC) measures for use in this area. These employ generating cancelling source(s) to destructively interfere with the unwanted source and thus result in a reduction in the level of the vibration at desired location(s). This is realised by detecting and processing the vibration by a suitable controller so that when superimposed on the disturbances cancellation occurs (Leitch and Tokhi, 1987). |
