    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»

    Gas servos are considered from a feedback analysis standpoint with emphasis on systems such as would be most suitable for missile application. Linearized equations are presented for the case where the piston is operating off-center. The basic stability and response problems are investigated and some of the characteristics of acceleration, pressure, and transient pressure feedback are considered. T... 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-...

    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 ... View full abstract»

  • Synthesis of third order contactor control systems

    Publication Year: 1959, Page(s): 109

    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...

  • Random sampling: Its effect on spectral density

    Publication Year: 1959, Page(s): 198

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (42 KB)

    There are sampled-data systems of interest in which the sampling intervals are random variables. An example is a track-while-scan radar with a non-ideal blip scan ratio. In the statistical design of such systems it may be necessary to compute the spectral density of a random signal at the output of a random sampler. If the sampling intervals are independent, this spectral density may be determined... 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»

    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»

    This paper describes a graphical method for synthesizing a compensation network where the fixed poles and zeros of the open-loop system are given and the closed-loop poles and zeros are independently specified. The resulting network is general in that it may have both real and complex poles and zeros. The method does not rely on cancellation techniques to determine the compensation network which i...

    This paper relates the pole-zero configuration of an error-sampled control system to the transient and steady-state response in a form amenable to straightforward synthesis procedures. The approximate transient response, as defined by percent overshoot and rise time, is specified for a generalized quadratic model in terms of readily discernable parameters. The steady-state error coefficients are d... View full abstract»

    I - Continuous-Time Systems - The "second method of Lyapunov is the most general approach currently in the theory of stability of dynamic systems. After a rigorous exposition of the fundamental concepts of this theory, applications are made to (a) stability of linear stationary, linear nonstationary, and nonlinear systems; (b) estimation of transient behavior; (c) control-system optimization; (d) ...

    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»

    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»

    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»

    Mathematical models are often needed for design and justification of computer control systems prior to installation. They may also become an integral part of the control system itself, providing a means for rapid and periodic determination of the best operating conditions. Using fundamental physical and chemical principles, relationships are written to describe typical process operations. Both ste... View full abstract»

    An attitude control system consisting of motor-driven inertial wheels in conjunction with an over-riding mass ejection system is proposed for use in space vehicles. Control by mass ejection is usedto compensate for initial distrubances during separation from the booster, and for removal of unwanted momentum stored in the wheels. The use of reaction wheels permits fine, damped attitude control. A l... View full abstract»

    Part I contains an evaluation of a proposal by O. J. M. Smith on the control, by Wiener prediction and a non-linear combination of input and feedback signals, of a saturating element driving a primarily inertial load. This evaluation consists of simulation tests on a high-speed analog computer with actual continuous random Gaussian inputs. Results presented include: (1) Variation of the mean squar...

    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»
