    An acceleration sensing instrument is essential to an automatic inertial navigation system. A velocity meter (VM) is a singly-integrating, acceleration-sensing instrument which has become important in providing precise, continuous velocity information for navigation of a wide variety of vehicles, from submarines to ballistic missiles. The increased autonavigator accuracy achievements and objective... View full abstract»

    This paper is concerned with the optimal computer control of a linear dynamic element of plant. It is required that the outputs of the plant exactly equal a set of desired outputs at the uniformly spaced time instants,t, t_{N}, t_{2N}, .... The system is optimal in the sense that a quadratic form of the control effort, which is proportional to the control energy, is a minimum. The optim... View full abstract»

    A study is made on the optimization of the adjustment process in a self-optimizing system under rather general assumptions. The system is designed to keep a performance parameter m either at a prescribed value or at an unknown extremal value. A direct measurement on m is made and the adjustment is based on measured m only. Factors considered are (1) the finite measuring interval, (2) the necessity... View full abstract»

  • Synthesis of third order contactor control systems

    Publication Year: 1959, Page(s): 109
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (46 KB)

    A dynamic system is given with a transfer function of third order (one real pole, two complex poles, and two zeroes). It is desired to design a contactor control which yields a near-optimum follow-up of a given input. For zero-seeking systems and for step-inputs an "optimum" control problem can be defined easily; however, a general solution of the optimum problem is not yet available. The known pa...

  • Topological techniques for the solution of multi-loop sampled systems

    Publication Year: 1959, Page(s): 108
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (34 KB)

    This paper presents a flow-graph approach for analyzing multiloop sampled-data systems. Two techniques for finding the sampled output are examined. These are, first, construction of a "sampled" signal flow graph from the original system; second, a general gain formula which can be directly applied to the original system. The theorems necessary to establish the formula are rigorously proved. The fi... View full abstract»

    The nervous control of heart rate in man was studied through dynamic analysis of experimental results and computer simulation. The heart rate changes caused by respiration were found to be accurately analyzable and predictable, as related by a fifth-order nonlinear differential equation which proved to have specific physiological meaning. The nonlinear characteristics of the equations are interest... View full abstract»

  • Signal stabilization of self-oscillating systems

    Publication Year: 1959, Page(s): 37
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (41 KB)

    The hunt (self-oscillations) of a physical system may often be removed by the introduction of an appropriate stabilizing signal which changes the open loop gain of a closed loop system in a non-linear manner. The theory of stabilization developed in this paper explains experimental results reported by R. Oldenburger in 1957. With the aid of Fourier series the designer can determine the periodic si...

    This paper deals with further advances of the author's recent work on optimal design of control systems and Wiener filters. Specifically, we consider the problem of designing a system to control a plant when (1) not all state variables are measurable, (2) the measured state variables are contaminated with noise, and (3) there are random disturbances. An explicit design procedure (well adapted to d... View full abstract»

    The rapid expansion of components and techniques for information conversion during recent years has provided control systems engineers with new tools for developing new kinds of systems. Nine basic functional tools have been identified which describe the complete information conversion process - sensing, converting, storing, communicating, computing, programming, regulating, actuating, and present...

    This paper describes the systems analysis and design of an automatic temperature control system in the world's largest fluid dynamics testing complex consuming 470 megawatts of drive power. The plant treated in this paper can be described mathematically as a 110th order system having 130 feedback loops. Facility component characteristics are mostly non-linear, with prominent distributed parameters... View full abstract»

    This report considers the general problem of obtaining the optimum multipole system when the inputs to the system are stationary random processes. The system under investigation is linear and time invariant. The input to each terminal shall consist of signal and noise. The synthesis procedure is carried out under the basis that a fixed plant must be compensated in order to perform certain desired ... View full abstract»

  • Calculating zeroes of functions arising in various control system problems

    Publication Year: 1959, Page(s): 197
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (43 KB)

    The paper considers three separate special cases of functions for which the zeroes are determined graphically. First, the spring constant of a structural member is replaced by a complex number to allow for hysteresis losses during vibration. The corresponding characteristic function has non-conjugate zeroes which are useful in calculating frequency response, but have no meaning for transient respo... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (35 KB)

    The human environment in space is controlled within fairly narrow limits, the range between the limits representing man's ability to adjust without serious strain. Broadly defined, environment includes the makeup of the gaseous artificial atmosphere, gas temperature, movement and humidity, the thermal radiation level, the mechanical force field, and the level of ionizing radiation. From the contro... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (728 KB)

    Control system feedback elements are subject to statistical variation from their desired characteristics due to manufacturing tolerances. For most feedback elements, this variation takes the form of a random nonlinear function of the input to the element. Analysis of the effects of such feedback errors is exceedingly difficult because the control system affected must be described by a random nonli... View full abstract»

    The problem of sensing and controlling the angular orientation of a space vehicle is discussed. Optical, radio, and inertial methods of angle-sensing are described, and application of control torques by reaction jets, flywheels, radiation pressure, and gravitational gradient are compared. Requirements for angular accuracy likely to be imposed by maneuvering, performing measurements for navigation,... View full abstract»

    Development of the basic theory of D-decomposition by a general polynomial expression, the characteristic function of a linear lumped parameter automatic control system, is followed by account of: the basic theory of parametric stability; unity-feedback variable-gain analysis, with subsequent generalization to numeric and frequency-dependent feedback; transient response determination; and sampled-...

    The reasons for using feedback are reviewed. The beneficial aspects of feedback are quantitatively expressed in sensitivity functions and noise transmission functions. The physical constraints on the controlled process (or plant) determine the maximum number of independent functions realizable. Any configuration with the same number of degrees of freedom may be used. With this approach the study o... View full abstract»

    Need for adaptive control systems is explained, and results obtainable with two forms are discussed. Recognized approaches to achieving self-adaptive action are indicated; integrating and nonintegrating techniques are compared. One non-integrating form, the model-bistable system, is taken as an example, and analysis of its operation is developed. Its application to flight control is described, and... View full abstract»
