Active flutter suppression: non-structured and structured H∞ design

Robust Control Design for Active Flutter Suppression

Flutter is an unstable oscillation caused by the interaction of aerodynamics and structural dynamics. It can lead to catastrophic failure and therefore must be strictly avoided. Weight reduction and aerodynamically efficient high aspect ratio wing design reduce structural stiffness and thus reduce flutter speed. Consequently, the use of active control systems to counter these adverse aeroservoe...

Latent Structured Active Learning

In this paper we present active learning algorithms in the context of structured prediction problems. To reduce the amount of labeling necessary to learn good models, our algorithms operate with weakly labeled data and we query additional examples based on entropies of local marginals, which are a good surrogate for uncertainty. We demonstrate the effectiveness of our approach in the task of 3D...

Making Structured Documents Active

Active documents result from a combination of some specific features in documents and some mechanisms in a document manipulation system. In this paper we present the possibilities offered by a structured model of documents and a structured editor for making active documents. Several applications are described (annotations, electronic indexes, cooperative editing, documents as user interfaces, e...
