To compare low-complexity distributed control schemes with multi-input multioutput (MIMO) control and to assess the results experimentally requires a test bed that is sufficiently complex to display on one hand the characteristic features of a distributed system, and yet is not too complex in order not to render the MIMO synthesis problem intractable. Here a 5m long aluminum beam, equipped with 16 collocated pairs of piezoelectric actuators and sensors, is used for vibration control experiments. A MIMO model obtained by finite element modeling techniques is presented and a distributed model in the spatially-interconnected systems framework is derived. Model reduction techniques are applied to the MIMO model and a centralized controller is designed to attenuate the vibration using H∞-loopshaping techniques. Finally, the performance of the controller is experimentally validated on the beam.||URI:||http://hdl.handle.net/11420/2486||ISBN:||978-150902873-3||Institute:||Regelungstechnik E-14||Type:||InProceedings (Aufsatz / Paper einer Konferenz etc.)|
