    Feedback controls based on the receding horizon method have proven to be a useful and easy tool in stabilizing linear ordinary differential systems. In this paper the receding horizon method is applied to linear systems with delay in the control. An open-loop optimal control which minimizes control energy subject to certain side constraints is first derived and then transformed to a closed-loop co... View full abstract»

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

    Request permission for commercial reuse | 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»

  • Pole assignment in single-input linear systems

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (296 KB)

    A computationally attractive procedure is given for calculating the feedback gain matrix required to place the poles of a single-input linear system at arbitrary locations. The method, applicable to uncontrollable as well as controllable ones, requires no explicit transformation of coordinates, nor does it require an a priori knowledge of the open-loop characteristic polynomial.

    Sufficient conditions for global and local controllability of certain types of nonlinear time-varying systems with implicit derivative are given. The results are obtained by using the notion of measure of noncompactness of a set and the Darbo fixed-point theorem. View full abstract»

    Parameter and state estimation algorithms have been applied to a hydrological model of a catchment area in southern Norway to yield improved control of the household of water resources and better economy and efficiency in the running of the power station, as experience proves since the system was installed on-line in the summer of 1978. A nonlinear conceptual state-space model of a Nordic hydrolog... View full abstract»

    The feedback control which achieves minimum-time transition to the state origin for nonoscillatory second-order plants with scalar saturable input involves a function of state raised to a power α which corresponds to the ratio of the plant eigenvalues. The feedback system is found to be acutely sensitive to variations in the parameter α, viz., the state origin cannot be reached in finite... View full abstract»

    We give some fairly general circumstances under which the experimental design problem for linear dynamic systems with correlated noise can be put in the exact form of the Kiefer-Wolfowitz experimental design problem. Optimal inputs are characterized in terms of their spectral measures with respect to a resolution of the identity in a certain reproducing kernel Hilbert space. Numerical methods esta...

  • Failure of the Routh-Hurwitz method of reduction

    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»

    The classical procedure for solving the economic dispatch problem in the presence of upper and lower limits on the generation levels may fail to lead to the constrained optimum generation schedule. In this paper a simple scheme suitable for real-time applications which resolves this drawback is presented. When transmission losses are neglected, the constrained optimum can be analytically computed ... 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»

    This paper considers observers of slow states in singularly perturbed systems. Upper bounds are derived on observer error due to use of a reduced-order model in the observer. This error is shown to be 0(μ), where the singular perturbation parameter μ is a measure of the separation between the slow and fast eigenvalues of the full-order system. View full abstract»

    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»
