An adaptive non-model based control logic for vibration suppression in flexible structures

Abstract

During the last decades, in order to reduce the vibrations in flexible structures, many active control strategies have been introduced. Among the other techniques, adaptive active controls are particularly attractive for time-varying and nonlinear systems. The goal of this work is to propose an adaptive version of Direct Velocity Feedback (DVF) using a non model-based identification system, which identifies the parameters of the mechanical system and uses them to set the gain of the control law.
