  • Regular implementability of nD systems: Results and open problems

    We study the problem of finding necessary and sufficient conditions for regular implementability by partial interconnection for nD system behaviors. In [3] such conditions were obtained in the context of ID systems. In the present paper we show that the conditions obtained in [3] are no longer valid in general in the nD context. We also show that under additional assumptions, the conditions still ... View full abstract»

    This article presents a implementation of a two- dimensional tracking filter in an automotive application. A headway alert system is a considered application for this tracking system, whose key component is a Kalman filter estimating and filtering two-dimensional trajectories of vehicles and various other obstacles that may occur in a traffic scenario. A reliable tracking system is essential for d... View full abstract»

  • Multidimensional filtering for movement analysis in image sequences

    Movement analysis of visual scenes can be performed by means of linear multidimensional filters, that have already been analyzed in the past. While soundness of results was convincing, interest in those systems declined due to the reduced computational abilities of contemporary computers. Modern hardware allows realization of velocity filters, if the n-D system is carefully adapted to the analysis... View full abstract»

  • State-space formulation of 2D frequency transformation for 2D digital filters

    Publication Year: 2007, Page(s):21 - 24
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (177 KB) | HTML iconHTML

    In this paper, a state-space formulation of 2D frequency transformation for 2D digital filters was derived. The obtained state-space formulation includes the well-known formulations of 1D frequency transformation for either 1D filters or 2D filters as special cases, and thus can be viewed as a natural generalization of these existing results to the general 2D case. A non-trivial example is given t... View full abstract»

  • An algorithm for SDV representation of 2D behaviors

    Publication Year: 2007, Page(s):25 - 31
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (153 KB) | HTML iconHTML

    This paper deals with the characterization of 2D behaviors that are representable by means of special first order models, known as state/driving-variable (SDV) models. In previous work, [1], [2] we have shown how to identify SDV-representable behaviors using one of its full row rank representations. Here, we give a further refinement by showing that a 2D behavior is SDV-representable if and only i... View full abstract»

    The notion of interconnection is the basis of control in the behavioral approach. In this setting, feedback interconnection of systems is based on the still more fundamental concept of regular interconnection, which has been introduced by J. C. Willems. In this paper, the following problem is addressed: given a plant, under what conditions does there exist a controller such that their interconnect... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (154 KB) | HTML iconHTML

    We discuss some ideas and preliminary results on the stability of nD systems described by linear constant coefficient PDE's. The stability concept used is Lscr2-stability and Lscr2-asymptotic stability, with time as a distinguished variable. For scalar equations, stability conditions are derived, including methods to make these conditions into LMI's in the system parameters. ... View full abstract»

    An optimal control problem described by the system of the second order linear ordinary differential equations with infinite time horizon and integral cost functional is considered. Basis of a variational method, sufficient conditions for a stability of considered system are given. In the final part of the paper, an existence result related to the strongly optimal processes is obtained. View full abstract»

    This paper gives new results on optimization and optimal control of discrete linear repetitive processes. These are for the class of so-called wave processes which have recently been introduced to describe physical examples which contain dynamics not captured by previously considered models.

  • A 2-DAE system gas network model in view to optimisation as a dynamic game

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (251 KB) | HTML iconHTML

    In this paper, we propose to model the optimisation of gas networks as a disturbed LQ game, where each player chooses his strategy according to a modified Nash condition under OL information structure. The dynamics in the network, as well as the coupling conditions, are modelled through a DAE system, and as a consequence a network with loops and nonpipe elements is considered. Conditions for the e... View full abstract»

  • Autonomy properties of multidimensional linear systems over rings

    Based on the notions of rank and reduced rank from commutative algebra, we discuss several aspects of the concept of autonomy for multidimensional discrete linear systems over finite rings of the form Z/mZ. We review several algebraic characterizations of autonomy that are equivalent for systems over fields and investigate their relationship in the ring case. The strongest of these notions turns o...

  • SUSAN edge detector reinterpreted, simplified and modified

    Our aim is to provide a new interpretation of the SUSAN edge detector and to propose its modified version, which is still simple, robust against errors and provides thinner edges, without further efforts on additional thinning. The new interpretation uses the idea of vertically weighted regression and in its simplest form it leads to interpreting USAN in terms of a box sliding on the surface of an... View full abstract»
