DESIGN OF REDUCED-ORDER u-CONTROLLER FOR FLEXIBLE STRUCTURES

Abstract

In this paper, u-controller based on a structured singular value is used
to reduce the vibration of the flexible structures having the transverse
and torsion vibrations. Meanwhile, in designing conffol system using
u -controller yields a controller with the order at least equal to the plant
order. Such controller often can not be used in practical application, thus
the order of controller is reduced by using the weighting balanced
realization.

Keywords: u-controller; flexible structures, weighting balanced
realization.
