    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»

    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»

    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...

    This note presents the first direct adaptive control structure for nonminimum phase systems where controller parameter identification can be posed as a standard linear parameter estimation problem. In particular, a linear equation error model is formulated for estimating both the controller parameters and some additional auxiliary parameters. The key idea involves insertion of the Bezout polynomia... View full abstract»

    A servo controller is designed so that the step response of the plant is as close as possible to that of a model system while the output regulation condition is satisfied. The controller is named "the model-following servo" and its control law is determined by optimization. The associated algorithm is presented. An example is included to illustrate the procedure.

    This paper is concerned with the solvability and controller synthesis of the robust servomechanism problem for a decentralized system subject to the constraint that each control agent of the system possesses only a limited knowledge of the model of the system to be regulated, i.e., typically, each agent of a large-scale system possesses only a local model of the system, which may be different from...

    Strict positive real (SPR) conditions for global convergence of stochastic adaptive control and recursive identification schemes have appeared in a number of analyses using different approaches. It is shown that this strict positive real condition on the unknown operator associated with the plant can be removed in every case by a sufficient overparameterization of the parameter vector.

    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...

    In the design of decentralized control systems it is well known that the existence of unstable fixed modes prevents us from stabilizing it via linear time-invariant local controllers. In this note, we show that such systems might be stabilizable via time-varying controllers. In particular, a design method using sample and hold is proposed. View full abstract»

    The system of kinematic equations which describes Isaacs' Game of Two Cars has been extended to the case of a three-dimensional pursuit-evasion game between players with bounded curvature. It is shown that in the three-dimensional version of the Homicidal Chauffeur game, both players, when playing optimally, strive to steer the system into a common plane and will remain on this plane until game te...
