    A number of investigations have been made in recent years about the transmission of Gaussian noise through nonlinear devices. In many cases, simplification or approximations were needed to make analytical solutions possible, and only zero-average Gaussian input signals were used when the results were applied to feedback control systems. This paper presents a different approach to the problem of no... View full abstract»

    The space stabilizing capability of a servo controlled nonrotating inertial mass is analyzed and its drift rate performance compared with a high precision gyroscope. The results indicate that the nongyroscopic inertial reference and guidance system exceeds the performance of gyroscopic systems by several orders of magnitude. It is shown that a servo system materially contributes to the drift accur... View full abstract»

    In many sampled-data systems the sampling interval T is "small" and the response r_{s}(t) closely approximates the response r(t) of the continuous system; one is then interested in evaluating the difference r_{s}(t) - r(t) for various values of T...

    A phase plane technique, which takes advantage of convenient relationships in other planes (for example, displacement versus time) to effect graphical solutions for a non-linear time varying second order differential equation, is developed. Several special cases of this general second order equation are considered. The special case of most practical importance occurs when the differential equation... View full abstract»

    In order to satisfy stringent performance requirements in a dynamic process, a computer is incorporated as a central element in the feedback loop. The computer performs the dual task of identifying or measuring the process dynamics, and thence generating an appropriate command or actuating signal so as to satisfy the overall specifications. The family of singularity functions (steps, ramps, conflu... View full abstract»

    An attempt is made in the subject paper to evolve a basic philosophy for adaptive control systems. A method is described for determining the system impulse response from measurements of instantaneous system input and output. The impulse response is expanded in a Taylor series, to facilitate solution of the convolution integral. From a knowledge of the impulse response and the system error, the nec... View full abstract»

    Maximum effort control is a method of achieving deadbeat response for a step input to an undamped second order element (two poles on the j\omega axis of the s-plane) which is preceded by a saturating amplifier. This method of control supplies the maximum available energy to the element being controlled, by driving the amplifier to saturation whenever an error... View full abstract»

    A method for the determination of the characteristic pole locations in simple systems and components is discussed. The techniques introduced are extended to include more complex systems. The method consists of applying a signal to the system from a "complex-zero-generator" and then observing the system output response on an oscillograph. The system pole locations are determined when the system out... View full abstract»

    The guidance and control accuracy of most aerodynamic and space vehicles is limited primarily by the noise disturbances which enter the guidance system. Present theory for the minimization of these noise effects does not take into account the forced kinematic time variations, such as is due to time-varying range, which occur in most guidance problems. Such time variations occur in interplanetary f... View full abstract»

    Knowing the frequency response of a linear system, a method is presented for obtaining the time response of the system to an impulse, step, or ramp function input, without performing graphical integrations. The transient response is of the form f(t) = \sum \min{i} A_{i}G(\omega _{i}t) where a different function G is use... View full abstract»

    One of the most challenging areas in the field of automatic control is the design of automatic control devices that 'learn' to improve their performamce based upon experience, i.e., that can adapt themselves to circumstances as they find them. The military and commercial implications of such devices are impressive, and interest in the two main areas of research in the field of control, the USA and... View full abstract»

    Coherent optical systems, which utilize the wave nature of light and the consequent diffraction phenomena, may often be used to supplement or even replace complex electronic equipment. Such systems are particularly adapted to the performance of certain linear mathematical operations, particularly those of an integral transform nature such as spectral analysis, convolution, auto- and cross-correlat...

    The following paper describes a method of obtaining a polynomial characteristic function for a nonlinear static system. This function, F(x) = hx + mx^{2} + dx^{3} , is obtained by the application of a growing exponential x = \exp(t) to the input of the system and the filtering of the output View full abstract»

    In many multi-stage decision processes we face the problem of dealing with random variables whoe distributions are initially imperfectly known, but which become known with increasing accuracy as the process continues. In this paper we shall show how Dynamic Programming may be used to treat a class of such problems, which are currently called adaptive processes. After discussing the general theory,...

    The powerful Laplace transform method for transient analysis by the partial fraction expansion technique has become quite popular in the fields of circuit and servo design. The theory of residues is usually used to find the coefficients of these fractions. The process is quite simple until second and higher order poles are included in the denominator. Previously, this has required a return to the ... View full abstract»

    This paper describes one very general approach to the design of adaptive control systems. The particular systems considered are process adaptive. The dynamic characteristics of the physical process are determined by the parameter tracking servo. The parameters thus determined are used to program the process' controller. The parameter tracking servo is a closed loop self-adjusting system. It consis... View full abstract»

    This paper is concerned with obtaining the optimum system in the Weiner sense for the multipole system. Earlier literature has shown how to obtain the mean-square value of the error when the multipole system transfer function has been specified, but thus far no published work has shown how to solve the synthesis problem, in general, for this case. The principal reason that this problem has appeare... View full abstract»

    The increasing applications of numerical control of processes have created a need for new methods of synthesis of control equipment. The method presented is applicable to systems commanded by discretely valued inputs, and processes whose outputs may be similarly quantized. Periodic sampling is not required. The most suitable sampling is by transmission of only significant data, as the new value ob... View full abstract»
