Robust control of a flexible system - covering parametric uncertainty with a non-parametric model

Abstract

In this paper we consider the robust control of a free-free Euler-Bernoulli beam model having 20% uncertainty in the modal frequencies. Using the H∞ design framework and non-parametric uncertainty models, we design for robust performance. The novelty of this work rests on the fact that we try to reduce the conservatism in using disks to cover the parametric uncertainty.
