Paper Abstract

The purpose of the study described in this paper is the development of a demonstrator of active vibration insulation through a composite active bar and the assessment of the performances of different control strategies and actuator technologies. The study consisted of three major steps, first the specification of the problem, secondly the design and implementation of the elements of the demonstrator, and last the performance evaluations. (1) its geometry representing a generic aerospace structure, (2) the frequency of the exciting vibrations limited to 1 kHz, (3) to be reconfigurable to allow different actuating technologies and different control strategies to be implemented. After the specifications the elements of the demonstrator were built and designed: it is based on a carbon fiber/epoxy resin composite tube and a digital controller with a digital signal processor with different control strategies such as filtered x-LMS. A complete description of all three steps is given as well as results of experiments.
