The purpose of this paper is to extend the work of Schandl in many respects: robust H1-control is applied instead of state-feedback, an optimal placement of actuators and sensors is performed, nonlinear actuator dynamics are modeled and compensated, and the feasibility of the proposed concept is demonstrated in laboratory experiments. Furthermore, the design steps of such an active vibration control system are illustrated and highlight the performance of the H1-controller. The theoretical
concepts for such a centralized H1-control design are by now well established and readily available. An incomplete list of standard textbooks covering this topic is given in Skogestad and Post-lethwaite (1996), Zhou, Doyle, and Glover (1996), Preumont
(1997), and Gawronski (2004). Furthermore, criteria for the optimal placement of actuators and sensors are given in Leleu,
AbouKandil, and Bonnasieux (2001) and Gawronski (2004).
