A Youla-Kucera parametrized adaptive feedforward compensator for active vibration control

Abstract : Adaptive feedforward broadband vibration (or noise) compensation is currently used when an image of the disturbance (i.e. a correlated measurement) is available. However, in most of the systems there is a "positive" feedback coupling between the compensator system and the measurement of the image of the disturbances. This may lead to the instability of the system. The paper proposes a new Youla Kucera parametrization of the compensator. The central compensator assures the stability of the system and its performances are enhanced in real time by the adaptation of the Q-parameters. An analysis of the resulting system is provided. The algorithm has been applied to an active vibration control (AVC) system and real time results are presented.
