Abstract

The vibration reduction in mechanical systems can be performed by means of active control strategies. For non-linear and time-varying systems, a suitable choice is the use of an adaptive feedback solution, in which the identification system is a fundamental part of the control scheme. In this work, a non-model-based identification system is proposed and its results are used to automatically set the gain of the Direct Velocity Feedback (DVF) control law. The proposed adaptive control algorithm has been tested on a smart structure represented by a carbon fibre plate instrumented with strain gauge, accelerometers and piezoelectric patches.
