    Retransmission policies are presented for the decentralized control of a multiaccess packet-switched broadcast channel. The policies have a simple recursive form yielding a Markov description of the system. Finite average delay is achieved for an infinite-population Poisson arrival model for any ratelambda < e^{-1}. It is proposed that the goal of retransmission policies should be to... View full abstract»

    Each of several agents updates his estimate of the same random variable whenever he makes a new observation or receives the estimate made by another agent. In turn, each agent transmits his estimate to a randomly chosen subset of the other agents. A subset of agents forms a communicating ring if for every pairunderline{m}, underline{p}of ring members, there is a sequence of ring members... View full abstract»

    This short paper considers the general Riccati matrix differential equation. It reviews and extends results on the characterization and existence of equilibrium solutions, establishes that the Riccati equation has at most one stable equilibrium solution ast rightarrow inftyort rightarrow -infty, and confines the region of attraction to this unique stable equilibrium solution ...

    Nonlinear systems subjected to Gaussian inputs are studied based on the Wiener-like stochastic functional Fourier series [1]. Analytic and nonanalytic cascade, bilinear, and feedback nonlinear structures are considered and theirnth-order Fourier-Hermite kernels are calculated analytically. The characteristic kernel features thus revealed are discussed as a guide to interpret data from m... View full abstract»

    The infinite zero structure of linear multivariable systems is investigated via the geometric approach. The basic tools used are the new concepts of almost (A, B)-invariant and almost controllability subspaces. These concepts permit advantageous geometric interpretation of infinite zeros. This interpretation is a natural generalization of the finite case. Connection is made with the Smi... View full abstract»

    This note shows how the Nyquist stability test for finite dimensional systems, subject to a one-parameter family of feedback compensators, extends to a class of distributed systems that belong to the algebrahat{B}(sigma_{0})^{p times m}introduced by Callier and Desoer. View full abstract»

    An effective method for estimation of the region of attraction of an equilibrium point in the plane is proposed in this note. This new method for stability analysis of the second-order nonlinear systemdot{x} = f(x);x(t_{0})=x_{0}, is based on the properties of phase flows and associated velocity fields. Several engineering examples have been solved which illustrate the useful... View full abstract»

    This technical note deals with the problem of parameterizing the class of deadbeat controllers for a given system through the minimum of parameters. It is shown that ifnandmare dimensions of the state vector and control vector, respectively, and the μi's are the controllability indexes, then almost the whole class of deadbeat controllers is explicitly paramete...

    In a publication by Y. P. Harn and C. T. Chen [1] a proof of a discrete stability test by using the Lyapunov method was given. In this note the main results obtained by the author in this direction in 1965 [6], [7] and the extensions and applications obtained partially with other authors since then and published in different journals [8]-[10] are surveyed. The similarity to the results in [1] is o... View full abstract»

    The general matrix Riccati equation is decomposed into product of two factors where the first one is determined independent of the second factor. Condition for existence of solution of the Riccati equation is given via this decomposition and the existence of solution of the self-adjoint matrix Riccati equation arising in optimal control and Kalman filtering is directly established from that condit...

    We consider distributed algorithms for solving dynamic programming problems whereby several processors participate simultaneously in the computation while maintaining coordination by information exchange via communication links. A model of asynchronous distributed computation is developed which requires very weak assumptions on the ordering of computations, the timing of information exchange, the ... View full abstract»

    This note develops an observer based on the slow reduced-order system of a time-varying full-order system. An upper bound μ*on the singular perturbation parameter μ is derived such that for μ smaller than μ*, the full-order system is stabilized by linear feedback of the observed slow state. The dependence of this bound on the system matrices and the observ... View full abstract»

    A multivariable design technique is described for use in the design of strip shape control systems. The main control problem stems from the uncertainty in the knowledge of the mill gain matrix. The effect of modeling errors is to introduce interaction into the imperfectly compensated system. The design technique involves squaring down the system to make it more robust in the presence of such error... View full abstract»

    The eigenvalue-assignment approach of Brogan [1], [2] is generalized and extended to the assignment of the entire closed-loop eigenstructure of linear multivariable systems. The set of assignable eigenvectors and generalized eigenvectors emerges naturally in the solution and is given, moreover, in an explicit parametric form. Two numerical examples are worked out to demonstrate the application of ... View full abstract»

    A new adaptive scheme for continuous-time model reference adaptive control systems is proposed. It is shown that this scheme allows us to increase the exponential rate of parameter convergence to an arbitrary, desired level subject to a sufficiently rich reference input and a sufficiently large adaptive gain, while retaining global stability of the overall system. For simplicity and brevity the re... View full abstract»

    This note points out that the model order selection criteria proposed earlier for Davison's and Marshall's reduced order models are not applicable in many of the practical cases. A new criterion is proposed to overcome the deficiencies of the earlier methods. View full abstract»
