This paper addresses the design and implementation
of different controllers on a 1/10 scaled flexible structure
experiment of a metro vehicle car body. The particular
controller design methods investigated are state vector feedback
control combined with a Kalman-filter and the μ-synthesis
procedure. Using experimental data it is shown, that with
both design methods the structural response to disturbances
can be reduced. Nevertheless, because of the fact that the
μ-synthesis takes into account the uncertainty associated
with the model of the structure as well as the fact that the
performance variables to be controlled are not identical to the
measurements a better performance is achieved in comparison to
the state feedback controller. At the same time the control costs
are considerably lower when the μ-synthesis controller is utilized.
