    The investigation of infinite electrical networks having no restrictions on their graphs other than countability and connectedness is a recent occurrence. The first rigorous analysis of locally finite purely resistive networks was published in 1971 by Flanders, and the subject has developed apace since then. This article summarizes the current status of the subject and points out some open questio... View full abstract»

    During the past five years, multilinear, multipower, and polynomic systems have become a most important area of applications and theoretical development. This paper starts with some typical examples and historical remarks. Using this background, it then proceeds to put the recent literature in perspective and to partially quantify some broad problem categories where intensive work is underway. View full abstract»

    This paper surveys the distributed system parameter identification problem and concludes that it can be treated as a series of largely independent subproblems, each of which must be considered in any attempt to treat the problem in applications. An approach is discussed which treats in a unified manner all the inherent subproblems. An annotated bibliography of the literature in the field analyzes ... View full abstract»

    Nonlinear systems which are governed by a finite number of ordinary differential equations with controls present constitute a large and important class models for practical purposes. In the last few years, there has been considerable progress in our understanding of this class of models. This is an expository paper devoted to surveying and explaining some of the main results currently available. B... View full abstract»

    Publication Year: 1976, Page(s):72 - 88
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1579 KB)

    Linear passive time-variable networks are investigated primarily through the use of distributional kernels as applied to the scattering matrix treated in the time domain. Necessary and sufficient conditions for passivity are obtained, and the scattering matrix is shown to be a measure satisfying an energy form constraint. Lossless constraints pertinent to synthesis are developed while networks con... View full abstract»

    The problem of factoring a positive Hermitian operator into the product of a causal operator and its adjoint is reviewed. Three classes of factorization are studied, miniphase factorization, regular factorization, and special factorzation. The former always exists, and a complete representation thereof is obtained in terms of the properties of reproducing kernel spaces. The regular factorization d... View full abstract»

  • The growing algebraic presence in systems engineering: An introduction

    Cited by:  Papers (8)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1456 KB)

    A great deal of what systems engineers do is rooted firmly in the concepts of modern algebra. Despite this fact, however, systems manipulations have often been carried out with little or no awareness of their basic algebraic nature. However, recent years have witnessed a growing cognizance of the intrinsic presence of algebra in systems theory, and this recognition has led not just to further unde... View full abstract»

    A Gaussian stochastic process (yt) with known covariance kernel is given: we investigate the generation of (yt) by means of Markovian schemes of the type dxt= F(t)xtdt + dwtyt= H(t)xt. Such a generation of (yt) as the "output of a linear dynamical system driven by white noise" is possible under certain finitene... View full abstract»

    A synthesis procedure for systems with a nonlinear time-varying constrained part (plant) with uncertain parameters, subjected to a finite set of deterministic command and disturbance inputs I = {iα} is presented. The design must guarantee that in response to iα, the system output cα∈ Sα, despite the plant uncertainty, where S View full abstract»

  • Scattering theory and linear least squares estimation—Part I: Continuous-time problems

    Cited by:  Papers (18)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (827 KB)

    The Riccati equation plays as important a role in scattering theory as it does in linear least squares estimation theory. However, in the scattering literature, a somewhat different framework of treating the Riccati equation has been developed. This framework is shown to be appropriate for estimation problems and makes possible simple derivations of known results as well as leading to several new ... View full abstract»

    We consider the stability of the feedback interconnection of possibly unstable n-input n-output subsystems whose interconnection is described by e1= u1- y2, e2= u2+ y1and yi= Gi(ei), i = 1,2. We give three theorems which simplify the stability tests. Theorem 1 deals with nonlinear time-varying subsys... View full abstract»

  • Systems with infinite-dimensional state space: The Hilbert space approach

    The control of infinite-dimensional systems has received much attention from engineers and even mathematicians. Realizability although first considered in [4] has been ignored until recently. Ironically enough while state-space systems theory was developing in the early 1960's a mathematical study of scattering and of non-self-adjoint operators produced a parallel theory which was infinite dimensi...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1854 KB)

    Linear multivariable-distributed systems and synthesis problems for lumped-distributed networks are analyzed. The methods used center around the invariant subspace theory of Helson-Lax and the theory of vectorial Hardy functions. State-space and transfer function models are studied and their relations analyzed. We single out a class of systems and networks with nonrational transfer functions (scat... View full abstract»

    The resistance value of two electrodes attached to two-dimensional regions with rotational antisymmetry is obtained using the rule when equipotentials and lines of flow are interchanged. This is an extension of a previous work [1] in which mirror antisymmetrical regions were treated. View full abstract»
