    We use the orthogonalizing property of the two-multiplier linear prediction lattice filter to construct ad-step ahead predictor in lattice form. The predictor generatesd-step forward and backward residuals in a recursive way and possesses most of the interesting properties of the basic one-step prediction lattice filter. An exact solution is presented first assuming a station... View full abstract»

    A polynomic operator can be represented asT= Ltauwhere τ is an imbedding of the input Hilbert resolution space into the appropriate Hilbert scale, andLis a mapping of the Hilbert resolution space that results from closing the span of the Hilbert scale with respect to a naturally defined inner product, into the output Hilbert resolution space. This paper demonstrates the ... View full abstract»

    A linear time-invariant system with commensurate delays is considered. The system is characterized by two matricesA(d)andB(d)overR[d](polynominal in the delay operatord). It is assumed that the pair (A, B) is reachable over the ringR[d]. A constructive procedure is derived which, for any initial conditions, finds a solution to syste... View full abstract»

  • A note on the recursions of multichannel complex subset autoregressions

    The recursive algorithm to select the optimum multivariate real subset autoregressive model (AR) [1] is generalized to apply to multichannel complex subset AR's. It is initiated by fitting all "forward" and "backward" one-lag AR's. The method then allows one to develop successively all complex subset AR's of sizek(the number of lags with nonzero coefficient matrices) from 1 toK View full abstract»

    The concept of complementary models for discrete-time linear finite-dimensional systems with correlated observation and process noise is developed. Using this concept, a new algorithm for the fixed interval smoothing problem is obtained. The new algorithm offers great flexibility with respect to changes in the initial state variancePi_{0}. Next, the relationship among the new smoothing ... View full abstract»

    This paper studies the design of proper compensators to achieve arbitrary denominator matrices in the unity feedback configuration. The problem is first transformed into a set of linear algebraic equations. Some conditions for the existence of proper compensators are then developed. The design is achieved by solving the set of linear algebraic equations and is believed to be much simpler than the ... View full abstract»

    The subject of this note is an improved algorithm for the switching of Type-I and Type-II structures in tracking servosystems. Unlike the traditional control laws, the proposed algorithm takes into account not only the error, but its derivative(s) as well. The suggested control rule can be easily realized and is based upon concepts of the theory of variable structure systems (VSS). The advantages ... View full abstract»

    We present an algorithm for obtaining approximate internal descriptions for a discrete-time control system, given a finite number of external experiments (input-output data). The system is required only to be causal, with a continuous input-output map. The experiments should be done in a prescribed way, with bounded inputs acting over a finite period of time. The approximation will be valid over t... View full abstract»

    A mixed method of model reduction is proposed; it is based on the differentiation method suggested by Gutman et al. [1] and on the usual Padé method. More precisely, the differentiation procedure is used to obtain the reduced-order denominator, thus ensuring stability preservation, while the numerator is obtained by matching the first MacLaurin expansion coefficients of the original system an...

    This paper considers two-power input-output maps which are continuous-time, impulsive, and time-invariant. Realizability, by a very general class of nonlinear differential systems, is characterized simply in terms of the symmetric Volterra transfer function. The characterization leads directly to a family of minimal-order realizations having the (feedforward) structure described by Crouch [6]. Mem... View full abstract»

    Recent progress in Stackelberg dynamic games concentrates on either the deterministic situations or partially nested stochastic problems. In this paper, a class of "nonnested' stochastic Stackelberg dynamic games, namely LOG additive incentive problems, is solved. By explicitly introducing two essential ideas-"matching answers" and "GPD phenomenon," each incentive problem can be converted into a s... View full abstract»

    A simple algorithm for obtaining the continued fraction quotients in the modified Cauer form (MCF) from the given system matrices in companion form is presented. In the sequel, the triple of all lower order models in companion form is directly obtained. A matrix method of obtaining the time-moments and Markov parameters from the MCF quotients is also outlined. Finally, it is shown that system redu... View full abstract»

    A detailed analysis of the disturbance rejection problem in single-input single-output linear systems is presented. The analysis is based on an external polynomial model and employs the algebra of polynomials. All solutions are expressed in a parametric form and solvability conditions are given for a number of constraints including those of internal stability and arbitrary pole placement. Measurab...

    Two approaches are proposed for on-line identification of parameters in a class of nonlinear discrete-time systems. The system is modeled by state equations in which state and input variables enter nonlinearly in general polynomial form, while unknown parameters and random disturbances enter linearly. All states and inputs must be observed with measurement errors represented by white Gaussian nois... View full abstract»
