The paper discusses a feedback adaptive control approach for active vibration systems in the presence of unknown narrow band disturbances. A direct adaptive control scheme based on the internal model principle and the use of Youla-Kucera parametriztion is proposed. This approach is comparatively evaluated with respect to an indirect adaptive control scheme based on the estimation of the disturbance model. Evaluation of the performance of the adaptive control is done in real time on an active suspension system
