  • A new tracker for air-to-air missile targets

    An extended Kalman filter is developed to aid the tracking of an air-to-air missile from a maneuvering target aircraft. The filter exploits knowledge of the dominant aerodynamically induced lift and drag forces of a nonthrusting missile employing proportional navigation guidance, and it also accounts for the dynamic lag and bandwidth effects of the missile seeker, guidance, and control systems.

    One of the most effective methods for solving the matrix equation AX+XB=C is the Bartels-Stewart algorithm. Key to this technique is the orthogonal reduction of A and B to triangular form using the QR algorithm for eigenvalues. A new method is pro... View full abstract»

  • Three-phase induction motor impulse drive method

    Publication Year: 1979 , Page(s): 834 - 842
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (776 KB)  

    A three-phase induction motor is successfully driven in a stepwise motion, that is, one small rotating angle of the motor shaft at a time. This is accomplished by applying a three-phase power source voltage in pulse form through thyristors to the primary winding of the motor. The drive method based on this entirely new principle is dubbed "impulse drive." It is classified into six types with somew... View full abstract»

  • An algorithm for tracking multiple targets

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1184 KB)  

    An algorithm for tracking multiple targets in a cluttered enviroment is developed. The algorithm is capable of initiating tracks, accounting for false or missing reports, and processing sets of dependent reports. As each measurement is received, probabilities are calculated for the hypotheses that the measurement came from previously known targets in a target file, or from a new target, or that th...

  • Eigenvalues of a matrix inside an ellipse and Chebyshev filter

    Cited by:  Papers (3)

    The conditions for a matrix to have all its eigenvalues inside an ellipse are obtained and explained in terms of a vector norm. A set of functions orthogonal on the ellipse is obtained and the relation between the Chebyshev filter and these functions is presented. The Butterworth filter is derived as a particular case.

    The partitioned estimation algorithms of Lainiotis for the linear continuous-time state estimation problem have been generalized in this paper in two important ways. First, the initial condition of the estimation problem can, using the results of this paper, be partitioned into the sum of an arbitrary number of jointly Gaussian random variables; and second, these jointly Gaussian random variables ...

  • A Schur method for solving algebraic Riccati equations

    Cited by:  Papers (155)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (960 KB)  

    In this paper a new algorithm for solving algebraic Riccati equations (both continuous-time and discrete-time versions) is presented. The method studied is a variant of the classical eigenvector approach and uses instead an appropriate set of Schur vectors, thereby gaining substantial numerical advantages. Considerable discussion is devoted to a number of numerical issues. The method is apparently... View full abstract»

  • Optimal nonuniform sampling interval and test-input design for identification of physiological systems from very limited data

    Cited by:  Papers (15)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (816 KB)  

    Optimal design of test-inputs and sampling intervals in experiments for linear system identification is treated as a nonlinear integer optimization problem. The criterion is a function of the Fisher information matrix, the inverse of which gives a lower bound for the covariance matrix of the parameter estimates. Emphasis is placed on optimum design of nonuniform data sampling intervals when experi... View full abstract»

    Motivated by considerations of optimal organizational form for a firm, a model is constructed that describes an organization as a team, each of whose members has access to the same basic information seen through noisy channels. The precision of the information received through the channels are the control parameters of the problem and serve to characterize the organization. A general linear-quadra... View full abstract»

    This paper develops a method for generating Pareto efficient trajectories that provide optimal tradeoffs between two conflicting attributes-the total energy consumed and the total time taken to complete each trajectory. Straightforward formulations of the multiobjective optimization problem in these attributes are difficult to solve because of certain nonlinearities in train models and certain con...

  • On the irreducibility condition in the structural controllability theorem

    Publication Year: 1979 , Page(s): 963 - 966
    Cited by:  Papers (7)

    It is known that the structural system (A,B) is structurally controllable if and only if the corresponding matrix [A B] is generically full rank and irreducible. In this paper it is shown that the irreducibility condition alone implies that every nonzero mode of (A,B) is generically controllable. This result provides an easy proof to the structural controllability theorem stated above. In addition... View full abstract»

    In this work it is shown that provided a certain positive real condition is satisfied, the AML recursion for the parameters of a scalar ARMAX time series model converges with probability one without the need of monitoring. Previous proofs of convergence had effectively required that the recursion be monitored. View full abstract»

    For linear systems with uncertain observations, we investigate the existence of recursive least-squares state estimators. The uncertainty in the observations is caused by a binary switching sequence γk, which is specified by a conditional probability distribution and which enters the observation equation as ...

  • New results in realization theory for linear time-varying analytic systems

    The realization of linear time-varying systems specified by an analytic weighting pattern is approached in a novel manner using an algebraic framework defined over the ring of analytic functions. Realizations are given by a state representation consisting of a first-order vector differential equation and an output equation, both with analytic coefficients. Various new criteria for realizability ar... View full abstract»

    The purpose of this paper is to develop a theory of smoothing for finite dimensional linear stochastic systems in the context of stochastic realization theory. The basic idea is to embed the given stochastic system in a class of similar systems all having the same output process and the same Kalman-Bucy filter. This class has a lattice structure with a smallest and a largest element; these two ele... View full abstract»
