Identification of Flexible Structures for Robust Control

Balas, Gary J.; Doyle, John C. (Institute of Electrical and Electronic Engineers, 1989-06)
This article documents our experience with modeling and identification of an experimental flexible structure for the purpose of control design, with the primary aim being to motivate some important research directions in ...

Robustness and Performance Trade-Offs in Control Design for Flexible Structures

Balas, Gary J.; Doyle, John C. (Institute of Electrical and Electronic Engineers, 1994-12)
Linear control design models for flexible structures are only an approximation to the “real” structural system. There are always modeling errors or uncertainty present. Descriptions of these uncertainties determine the ...

Optical Flow: A Curve Evolution Approach

Kumar, Arun; Tannenbaum, Allen; Balas, Gary J. (Institute of Electrical and Electronic Engineers, 1996-04)
A novel approach for the computation of optical flow based on an L1 type minimization is presented. It is shown that the approach has inherent advantages since it does not smooth the flow-velocity across the edges and hence ...

A Comparison between Hankel Norms and Induced System Norms

Lu, Wayne W.; Balas, Gary J. (Institute of Electrical and Electronic Engineers, 1998-11)
A general definition is formulated for the Hankel norms as the induced norms of a strictly proper stable linear time-invariant (LTIV) system mapping vector-valued Lp-past inputs to vector-valued Lq-future outputs. Some ...

A Variational Approach to ℋ∞ Control with Transients

Lu, Wayne W.; Balas, Gary J.; Lee, E.B. (Institute of Electrical and Electronic Engineers, 1999-10)
This paper presents a variational approach to ℋ∞ control with transients in the state feedback case. The approach here provides a precise description with equality, instead of inequality, in the necessary and sufficient ...
