“…Analyses were derived for the beam dimensions, as well as the sensor and actuator positioning. In general, non-collocated systems suffer from a lack of robustness and should not be used if the uncertainty of the system is large [4], but the controller performance may be better than for collocated systems if a sufficiently accurate mathematical model is available [9].

This paper presents an experiment for active vibration control of a flexible beam structure in a laboratory setting. The purpose of the experiment is to give the students opportunity to understand the concept of active vibration control while working on complex dynamic problems including analytical modeling, data based modeling, model reduction, model validation, and closed-loop control. The piezoelectric patch actuators bonded to the beam surface give the students opportunity to design different control algorithms and test their efficiency. Some results concerning experimental modeling, model reduction and controller design are presented in the paper. The complexity of the system, unifying different engineering areas, requires multidisciplinary knowledge from the students to develop active vibration control concepts. Some lessons learned during developing and workings with this experimental setup are presented in the paper as well.

“…In this study, four stack actuators are considered in the full-size car body simulations (see Section 3 and Figure 1), whereas two stack actuators are utilized in the experimental setup in Section 3.4, see Figure 25. For more detailed studies on the actuator concept refer to Kozek et al (2011); the deformation characteristics of a simple console interface structure with a large-scale Piezo stack actuator have been investigated in .…”

“…An LQG controller is designed for a reduced-order plant model with 28 states (the system is identified with 200 states, see Kozek et al (2011)). Hence the system is transformed into a modal state space representation and all eigenmodes with an eigenfrequency higher than f ≈ 75 Hz are truncated and not considered for the controller design.…”
