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 ...

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 ...

Sensor Selection Via Closed-Loop Control Objectives

Balas, Gary J.; Young, Peter Michael (Institute of Electrical and Electronic Engineers, 1999-11)
The ability to stabilize a system and achieve performance objectives using active feedback control is highly dependent on the location, quality, type, and number of control actuators and sensors. One role of a control ...
