Abstract

The aim of this paper is to design and experimentally evaluate the performance of a feedback controller for vibration suppression of a flexible beam. The controller is designed to minimize the spatial H2 norm of the closed-loop system to ensure average reduction of vibration throughout the entire structure. In this work, the controller is designed to suppress the vibrations of the first six bending modes of the beam using a collocated piezoelectric actuator-sensor pair attached to the beam. Feedthrough terms are incorporated into the flexible-structure model to correct the locations of the in-bandwidth zeros. It is shown that the spatial H2 control has an advantage over the pointwise H2 control in minimizing the vibration of the entire structure. This control design methodology can be applied to more general structural vibration suppression problems.
