Abrupt and incipient fault isolation of nonlinear uncertain systems
(2000)This paper presents a robust fault diagnosis scheme for abrupt and incipient faults in nonlinear uncertain dynamical systems. A detection and approximation estimator is used for online health monitoring. Once a fault is ...

Adaptive control of a class of slowly time varying systems with modeling uncertainties
(2005)In a recent work, a new linear adaptive controller based on certainty-equivalence and backstepping design, which promises a level of transient and asymptotic performance comparable to that of the tuning functions adaptive ...

Adaptive LQ control with anti-windup augmentation to optimize UAV performance in autonomous soaring applications
(2008)The performance of a glider can be considerably improved by means of soaring and optimization of its trajectory. Recent advances in the area of static soaring assume known linear glider dynamics and no actuator saturation ...

Adaptive sliding mode control of a hypersonic flight vehicle
(2001)A Multi Input Multi Output (MIMO) adaptive sliding controller is designed and analyzed for the longitudinal dynamics of a generic hypersonic air vehicle. This vehicle model is highly nonlinear, multivariable, unstable and ...

Capacity of gaussian channels with noise uncertainty
(2004)In this paper the problem of defining, and computing the capacity of a communication channel when the statistic of an additive noise is not fully known, is addressed. The communication channel is specified as a continuous ...

Characterization of the Optimal Disturbance Attenuation for Nonlinear Stochastic Uncertain Systems
(2003)This paper is concerned with an abstract formulation of stochastic optimal control systems, in which uncertainty is described by a relative entropy constraint between the nominal measure and the uncertain measure, while ...

Determination of the jet energy scale at the Collider Detector at Fermilab
(2006)A precise determination of the energy scale of jets at the Collider Detector at Fermilab at the Tevatron p over(p, -) collider is described. Jets are used in many analyses to estimate the energies of partons resulting from ...

Entropy maximization as a holistic design principle for complex optimal networks
(2006)A general holistic theory is presented for the organization of complex networks. The theory proposes that complex networks, both human-engineered and naturally evolved, are organized to meet certain design or survival ...

Longitudinal motion control of air-breathing hypersonic vehicles based on time-varying models
(2006)The non-standard dynamic characteristics of air-breathing hypersonic flight vehicles together with the aerodynamic effects of hypersonic flight make the flight control of such systems highly challenging. Moreover the wide ...

Measurement of the ratios of branching fractions B(Bs0→Ds- π+π+π-)/B(B0→D-π+π+π-) and B(Bs0→Ds-π+)/ B(B0→D-π+)
(2007)Using 355pb-1 of data collected by the CDF II detector in pp̄ collisions at s=1.96TeV at the Fermilab Tevatron, we study the fully reconstructed hadronic decays B(s)0→D(s)-π+ and B(s)0→D(s)- π+π+π-. We present the first ...

MIMO disturbance and plant uncertainty attenuation by feedback
(2002)This paper investigates the ability of feedback to reduce plant and disturbance uncertainties in the MIMO case, by solving two fundamental problems posed by Zames in the late seventies. The approach used here is Banach ...

Minimax games for stochastic systems subject to relative entropy uncertainty: Applications to SDEs on Hilbert spaces
(2007)In this paper, we consider minimax games for stochastic uncertain systems with the pay-off being a nonlinear functional of the uncertain measure where the uncertainty is measured in terms of relative entropy between the ...
