  • Shearing optimization of the rolled billet according to a minimum waste criterion

    Publication Year: 1980 , Page(s): 225 - 229
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (440 KB)  

    The purpose of this paper is to resolve the control problem of shearing a rolled billet. The appropriate control should result in shearing each section to a length which consists of a predetermined basic length and a tolerance. The control should be effected with the minimum waste criterion. Because the final length of the rolled billet to be cut is not known, the control is based on the predictio... View full abstract»

  • Stable feedback control of bilinear systems

    In this paper, we present a feedback control law for a class of bilinear plant. It exhibits a bang-bang structure using a linear switching function. Asymptotic stability of the closed-loop system is derived by applying a generalized version of the Lyapunov's direct method. The primary advantage of our approach lies in its simplicity, indicating that the field of potential applications is quite wid... View full abstract»

  • On the generalized nyquist stability criterion

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (904 KB)  

    This paper starts with a straightforward self-contained treatment of the generalized Nyquist stability criterion based on the eigenloci of the open-loop transfer function matrix. The derivation is straightforward and does not invoke algebraic function theory, branch cuts, and Riemann surfaces. A similar criterion is derived for the distributed case where the open-loop transfer function matrices be... View full abstract»

  • A comparison of Lyapunov and hyperstability approaches to adaptive control of continuous systems

    Cited by:  Papers (13)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (552 KB)  

    This paper contains a brief survey of certain aspects of Lyapunov's stability theory and the hyperstability theory. Conditions which have to be satisfied for the two approaches to be successfully applied to adaptive observers and controllers are examined. When all the signals in the plant are uniformly bounded (as in adaptive observers and some control problems) the two approaches yield the same r... View full abstract»

  • A new form of the extended Kalman filter for parameter estimation in linear systems with correlated noise

    A well-known method for estimation of parameters in linear systems with correlated noise is the extended Kalman filter where the unknown parameters are estimated as a part of an enlarged state vector. To avoid the computational burden in determining the state estimates when only the parameter estimates are required, a new simple form of the extended Kalman filter, where the state consists only of ...

  • On minimal canonical realization from input-output data sequences

    An algorithm is presented for determining the state model of a discrete system from input-output a data in canonical form. The proposed method is based on a canonical input-output representation from which the Input matrix and the nondynamic part can be found by a simple recursive relation. View full abstract»

  • A scaling theory for linear systems

    In this paper we develop a theory of scaling for rational (transfer) functions in terms of transformation groups. In particular, we identify two different four-parameter scaling groups which play natural roles in studying linear systems and investigate the effect of scaling on Fisher information and related statistical measures in system identification. The scalings considered include change of ti... View full abstract»

    We are often faced with the problem of estimating the number of parameters, as well as their values, for a model that will fit a given set of observations. An important study of this identification problem was made by Akaike, who improved the maximum likelihood principle and established the so-called AIC criterion to select suitable models. This criterion has been applied extensively to constant c... View full abstract»

  • Algorithms for multicriterion optimization

    In this paper we report new methods for obtaining a noninferior solution to a multicriterion optimization problem. Unlike existing methods, which convert vector-valued optimization problems into scalar-valued ones, our methods treat the multiple objectives as they are, without employing an artificial single objective. Each of the new methods is readily implementable and convergent to a local nonin... View full abstract»

  • Mixed Stackelberg strategies in continuous-kernel games

    Publication Year: 1980 , Page(s): 307 - 309
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (304 KB)  

    It is shown that continuous-kernel nonzero-sum games with compact strategy spaces could admit both pure and mixed Stackelberg equilibrium solutions, if the cost function of each player is either nonquadratic or nonconvex in his own decision variable. In such a case, the mixed Stackelberg strategy will yield a lower average cost for the leader than the pure Stackelberg strategy. It is also verified... View full abstract»

    This paper considers the problem of matching the transfer function matrix of a given two-dimensional system to that of a desired two-dimensional model using output feedback. The approach followed is essentially based on the idea of equating the coefficients of the like w^{i}z^{j} terms in the relationship T_{c}(w,z)= T_{m}...

    This paper presents a method of extending computation beyond the limit of the initial normal interval in Walsh series analysis of dynamical systems. The solution may be extended over contiguous normalized intervals of time to any length. The procedure avoids operational matrices of prohibitively large size and reduces the computational effort to a minimum while retaining accuracy. As a by-product ... View full abstract»

    We provide a tutorial introduction to certain numerical computations both in linear algebra and linear systems in the context of bounded arithmetic. The essential characteristics of bounded arithmetic are discussed in an introductory section followed by a review of the fundamental concepts of numerical stability and conditioning. The singular value decomposition (SVD) is then presented along with ... View full abstract»

    The Routh-Hurwitz reduction method is shown to have a serious disadvantage in that the reduced model may approximate the nondominant poles of the system and hence lead to erroneous approximations. A numerical example is given to compare the Routh-Hurwitz method to the Padé approximation method. View full abstract»
