Active vibration suppression in smart structures subjected to model uncertainties and environmental disturbances: An adaptive approach

Abstract

This paper presents a novel adaptive-based vibration control algorithm for smart structures, despite the model parameter variations, unstructured uncertainties, and environmental disturbances. The rate of vibration suppression can be managed in the proposed method, by taking a desired exponential decaying trajectory. Since the proposed method is established by taking various perturbations into account, it can be applied to a wide class of structures without any conservative hypotheses. The stability analysis is presented based on the Lyapunov's direct method. In order to verify the effectiveness of the method, numerical analyses are presented and discussed by applying the developed vibration control methodology to a smart beam. © 2012 The Author(s).
