[20120413] A dynamical adaptive resonance architecture
A set of nonlinear differential equations that describe the dynamics of the ART1 model are presented, along with the motivation for their use. These equations are extensions of those developed by Carpenter and Grossberg ... 
[20120413] Static output feedback: a survey
This paper reviews the static output feedback problem in the control of linear, timeinvariant (LTI) systems. It includes analytical and computational methods and presents in a unified fashion, the knowledge gained in the ... 
[20120413] Phaseconvex arcs in root space and their application to robust SPR problem
This paper considers the problem of identifying regions in the complexplane, such that the phase of polynomials having roots in those regions, is bounded by that of a few extreme polynomials. Applications of the results ... 
[20120413] Identification and control methods for high power electron beamdriven microwave tubes
The goal of this paper is to introduce some identification and control systems concepts to the field of high power microwave (HPM) tubes. These concepts are well known to the control systems community, but have not yet ... 
[20120413] Experimental results in robust lateral control of highway vehicles
Vehicle lateral dynamics are affected by vehicle mass, longitudinal velocity, vehicle inertia, and the cornering stiffness of the tires. All of these parameters are subject to variation, even over the course of a single ... 
[20120413] Interpolation with bounded real rational units with applications to simultaneous stabilization
In this paper we present sufficient conditions for the existence of a bounded real rational unit in H∞ to exactly interpolate to points in the right half plane (RHP). It is shown that these sufficient conditions are ... 
[20120413] A neuralnetwork model of the input/output characteristics of a highpower backward wave oscillator
This paper discusses an approach to model the input/output characteristics of the Sinus6 electron beam acceleratordriven backward wave oscillator. Since the Sinus6 is extremely fast to warrant the inclusion of dynamical ... 
[20120413] Common, multiple and parametric Lyapunov functions for a class of hybrid dynamical systems
This paper considers Lyapunov stability of discontinuous dynamical systems. It is assumed that discontinuities in the system dynamics are caused by some internal (e.g. component failures), and/or external (e.g. controller ... 
[20120413] Nonlinear observer design using dynamic recurrent neural networks
A nonlinear observer for a general class of singleoutput nonlinear systems is proposed based on a generalized dynamic recurrent neural network (DRNN). The neural network (NN) weights in the observer are tuned online, with ... 
[20120412] Implementation of a frequencyagile, high power backward wave oscillator
Work at the University of New Mexico (UNM) has demonstrated how finite length effects in a high power vacuum backward wave oscillator (BWO) can be exploited to achieve frequency agility for constant beam and magnetic field ... 
[20120412] Interactive DSP course development/teaching environment
The authors have developed an interactive environment for the creation and maintenance of dynamic, active multimediabased teaching mechanisms. The environment is designed to be userfriendly and to facilitate the creation ... 
[20120412] On the control of a high power backwardwave oscillator using quantifier elimination methods
This paper presents an experimental/theoretical study of methods to identify and control a repetitivelypulsed high power microwave source. A neural network was used to model the system and quantifier elimination (QE) ... 
[20120412] Neural networks in fault detection: a case study
We study the applications of neural nets in the area of fault detection in real vibrational data. The study is one of the first to include a large set of real vibrational data and to illustrate the potential as well as the ... 
[20120412] Robust multiobjective feedback design via combined quantifier elimination and discretization
This paper deals with the application of computerized quantifier elimination (QE) methods for robust multiobjective feedback design, when design objectives are specified in the frequency domain. The class of design problems ... 
[20120412] Linearquadratic simultaneous performance design
In this paper the problem of designing a fixed state feedback control law which minimizes an upper bound on linearquadratic performance measures for m distinct plants is reduced to a convex programming problem. 
[20120412] On the stability of LAPART
In this paper we show how the stability of a LAPART neural network can be deduced as a result of a general theorem on the input/output stability of nonlinear systems. This result gives conditions on how to choose certain ... 
[20120412] A unification between nonlinearnonquadratic optimal control and integrator backstepping
In this paper we develop an optimalitybased framework for backstepping controllers. Specifically, using a nonlinearnonquadratic optimal control framework we develop a family of globally stabilizing backstepping controllers ... 
[20120412] Robust finitetime stability design via linear matrix inequalities
For linear systems with polytopic uncertainties, the problem of robust finitetime stabilization is reduced to a system of Linear Matric Inequalities. 
[20120412] Analytic Gain and Phase Margin Design
In 5, algorithms are presented for analytic gain and phase margin design. Without special care however, the compensator computed with this algorithm is not a real rational function. In 3, it is shown that with some care, ...
