Adaptive robust sampled-data control of a class of systems under structured perturbations
(IEEE, 1993)Robust adaptive sampled-data control of a class of linear systems under structured perturbations is considered. The controller is a time-varying state-feedback law having a fixed structure, containing an adjustable parameter, ... -
A capacitated hub location problem under hose demand uncertainty
(Elsevier, 2017)In this study, we consider a capacitated multiple allocation hub location problem with hose demand uncertainty. Since the routing cost is a function of demand and capacity constraints are imposed on hubs, demand uncertainty ... -
Discrete-time LQ optimal repetitive control
(IEEE, 1999)LQ optimal repetitive control is developed in single-input single-output discrete-time signal/system framework. For a given plant and a stabilizing controller, the LQ optimal repetitive control system can be obtained by ... -
Evidential logical sensing using multiple sonars for the identification of target primitives in a mobile robot's environment
(IEEE, 1996)Physical models are used to model reflections from target primitives commonly encountered in mobile robot applications. These targets are differentiated by employing a multi-transducer pulse/echo system which relies on ... -
Experimental study of linear closed-loop control of subsonic cavity flow
(2006)A study is presented of the modeling and implementation of different concepts for linear feedback control of a single-mode resonance shallow cavity flow. When a physics-based linear model is used for cavity pressure ... -
Eye tracking using markov models
(IEEE, 2004)We propose an eye detection and tracking method based on color and geometrical features of the human face using a monocular camera. In this method a decision is made on whether the eyes are closed or not and, using a Markov ... -
A histogram-based approach for object-based query-by-shape-and-color in image and video databases
(Elsevier, 2005)Considering the fact that querying by low-level object features is essential in image and video data, an efficient approach for querying and retrieval by shape and color is proposed. The approach employs three specialized ... -
H∞-performance analysis of robust controllers designed for AQM
(IEEE, 2003)It has been shown that the TCP connections through the congested routers with the Active Queue Management (AQM) can be modeled as a nonlinear feedback system. In this paper, we design H∞ robust controllers for AQM based ... -
Identification of insect damaged wheat kernels using transmittance images
(IEEE, 2004)We used transmittance images and different learning algorithms to classify insect damaged and un-damaged wheat kernels. Using the histogram of the pixels of the wheat images as the feature, and the linear model as the ... -
Is there a flight to quality due to inflation uncertainty?
(Elsevier BV, 2005)After two types of inflation uncertainty are derived within a time-varying parameter model with GARCH specification, the relationship between inflation uncertainty and interest rates for safe assets is investigated. The ... -
Line spectral frequency representation of subbands for speech recognition
(1995)In this paper, a new set of speech feature parameters is constructed from subband analysis based Line Spectral Frequencies (LSFs). The speech signal is divided into several subbands and the resulting subsignals are represented ... -
Local convex directions for Hurwitz stable polynomials
(IEEE, 2002)A new condition for a polynomial p(s) to be a local convex direction for a Hurwitz stable polynomial q(s) is derived. The condition is in terms of polynomials associated with the even and odd parts of p(s) and q(s), and ... -
Low dimensional modelling and Dirichlét boundary controller design for Burgers equation
(Taylor & Francis, 2004)Modelling and boundary control for the Burgers equation is studied in this paper. Modelling has been done via processing of numerical observations through proper orthogonal decomposition (POD) with Galerkin projection. ... -
A model-based scheme for anticontrol of some chaotic systems
(World Scientific Publishing, 2003)We consider a model-based approach for the anticontrol of some continuous time systems. We assume the existence of a chaotic model in an appropriate form. By using a suitable input, we match the dynamics of the controlled ... -

(IEEE, 2003)Recently it has been shown that the AQM (Active Queue Management) schemes implemented in the routers of communication networks supporting TCP (Transmission Control Protocol) flows can be modeled as a feedback control system. ... -
On the stabilization and stability robustness against small delays of some damped wave equations
(IEEE, 1995)In this note we consider a system which can be modeled by two different one-dimensional damped wave equations in a bounded domain, both parameterized by a nonnegative damping constant. We assume that the system is fixed ... -
Plant Order Reduction for Controller Design
(IEEE, 2003-06)Two dual methods of plant order reduction for controller design are proposed for linear, time-invariant, multi-input multi-output systems. The model reduction methods are tailored towards closed-loop stability and performance ... -
Robust adaptive stabilization of a class of systems under structured nonlinear perturbations with application to interconnected systems
(Taylor & Francis, 1996)This paper presents a stabilization scheme for a dass of multi-input/multioutput systems with nonlinear additive perturbations using high-gain adaptive controllers The nominal system is assumed to satisfy some mild conditions ... -
Robust antiwindup compensation for high-precision tracking of a piezoelectric nanostage
(Institute of Electrical and Electronics Engineers Inc., 2016)Ultrahigh-precision tracking in nanomanipulations poses major challenges for mechanical design as well as servo control, due to the general confliction between the precision requirement and large stroke tracking. The ...
