    The initials IFAC, standing for the International Federation of Automatic Control, are appearing more and more in the control systems literature these days. It is appropriate that readers of these TRAHSACTIONS be more fully aware of this organization in which they participate through the IRE's membership in the American Automatic Control Council. What are IFAC's purposes, who are its members, how ... View full abstract»

    In many engineering, economic, biological, and statistical control processes, a decision-making device is called upon to perform tinder various conditions of uncertainty regarding underlying physical processes. These conditions range from complete knowledge to total ignorance. As the process unfolds, additional information may become available to the controlling element, which then has the possibi...

  • The properties and methods for computation of exponentially-mapped-past statistical variables

    Publication Year: 1960, Page(s):11 - 17

    The exponentially-mapped-past (emp) statistical variables represent an approach to the statistical analysis of a process when the interest is focused on the recent behavior of the process. An exponential weighting function, decreasing into the past, in the case of continuously observed processes, and a geometric ratio, in the case of discrete data, are utilized. This approach is the simplest from ... View full abstract»

  • Generalized weighting function and restricted stability of a linear pulse-modulated error feedback system

    Publication Year: 1960, Page(s):18 - 24

    A generalized weighting function is obtained for a linear feedback system with a pulse-modulated error signal. This is expressed in the form of a matrix operator acting on an input vector, the components of which are the first R − 1 derivatives of the input, where R is the order of the unmodulated closed-loop system. In addition, since the system operator takes the form of a finite dimensio... View full abstract»

  • Optimization based on a square-error criterion with an arbitrary weighting function

    Several important criteria for the performance of communication systems and control systems are reviewed, and a new criterion (the mean-weighted-square-error criterion) is then introtroduced. This is shown to be a special form of a very general criterion proposed earlier, but to have special significance in that it is a generalization of the familiar mean-square-error criterion. The minimization o... View full abstract»

  • Multiple-rate sampled-data systems

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (6972 KB)

    The characterization of multiple-rate sampled-data systems by the ordinary z-transform of single-rate systems is shown. Single-rate sampling, or impulse modulation, of continuous signals is performed by an impulse modulator, M; the sampled, or “starred,” function is described by the z-transform. In an analogous manner, a submultiple-rate modulator is introduced; its presence in a bra... View full abstract»

  • Automatic control of three-dimensional vector quantities — Part 2

    In Part 1 of this paper13 a vector algebra was developed using a three-element column matrix to represent the vector, and a three-by-three matrix to represent a vector transformation operator. Problems in spherical trigonometry were analyzed with the use of a position vector, and the design of automatic computers to solve such problems was considered. In Part 2, the angular velocity vec...

  • Root locus properties and sensitivity relations in control systems

    The differential properties of root loci including pole sensitivity, angle of slope, and curvature at ordinary and irregular points are investigated in a unified manner. A relation between the sensitivity function and pole sensitivity is established. The sensitivity is shown to determine variations in the transfer function due to large (not only infinitesimal) variations in K. Additional propertie... View full abstract»

    In a recent issue of these Transactions, Weiss1 has given an excellent annotated bibliography on the subject of transportation lag. He was kind enough to refer to a previous bibliography which appeared in this author's thesis (his reference number [Ch 5]). Since the latter is not generally available, the bibliography therein is given here. The items which have already appeared in Weiss'... View full abstract»
