Least-correlation estimates for errors-in-variables models
(John Wiley & Sons, Ltd., 2006-09)
This paper introduces an estimator for errors-in-variables models in which all measurements are corrupted by noise. The necessary and sufficient condition minimizing a criterion, defined by squaring the empirical correlation ...
Nonlinear feedback control with global stabilization
(Kluwer Academic Publishers; Springer Science+Business Media, 1995-10)
Hamilton-Jacobi-Bellman theory is shown to provide a unified framework for nonlinear feedback control laws for special classes of nonlinear systems. These classes include Jurdjevic-Quinn type systems, as well as minimum ...
Attitude stabilization of a rigid spacecraft using two control torques: A nonlinear control approach based on the spacecraft attitude dynamics
(Elsevier, 1994-06)
The attitude stabilization problem of a rigid spacecraft using control torques supplied by gas jet actuators about only two of its principal axes is considered. If the uncontrolled principal axis of the spacecraft is not ...
Fixed-structure robust controller synthesis via decentralized static output feedback
(John Wiley & Sons, Ltd., 1998-05)
This paper describes and illustrates a unified methodology for robust, fixed-structure controller synthesis. The approach is based upon direct fixed-structure controller synthesis using a decentralized static output feedback ...
Global Asymptotic Stabilization of a Spinning Top With Torque Actuators Using Stereographic Projection
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-07)
The dynamical equations for a spinning top are derived in which theorientation is specified by a complex variable using stereographic projectionof Poisson's equations. Necessary and sufficient conditions for Lyapunovstability ...
