    The structure of optimum control systems and the form of the optimal control signals are discussed for minimum time, minimum fuel, and minimum energy control of linear time-invariant plants. If the control variables are bounded by 1 in magnitude, then the control signals must have the values +1 or ¿1 for minimum time response; +1, 0, or ¿1 for minimum fuel operation; +1, ¿1 or be linearly relat...

    Networks of certain types of time-varying circuit elements can be treated analytically in essentially the same way as networks of fixed-parameter elements, and for such networks the known theory of network analysis and synthesis of fixed-parameter elements can be considered as a special case of a more general theory. A few of the details of the extension to the general theory are considered, and a... View full abstract»

    A simple technique is introduced for calculating the kernels in the Volterra series expansion, which represents the solution of a large class of nonlinear differential equations. The Volterra series considered in previous discussions can represent only solutions with zero initial conditions. The scope is widened in this paper to allow representation of the general solution of nonlinear differentia... View full abstract»

  • An approach to the economic evaluation of electric power generation in continuous-process plants

    Publication Year: 1963, Page(s):335 - 339
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1318 KB)

    This paper is not intended to present a case either for or against industrial generation of electric power. It is intended only as a guide to objectivity in determining the true merits of any such proposal. An attempt has been made to point out some of those factors which are too often neglected or insufficiently weighed in economic evaluations of by-product electric power generation projects, and...

  • Twin-T compensation using root locus methods

    Publication Year: 1963, Page(s):339 - 350
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2025 KB)

    Techniques are described for the rapid synthesis of twin-T RC (resistance capacitance) networks with specified singularities. The twin-T network can be used to generate a pair of complex zeros that lie at any specified points in the left-half portion of the s-plane and under certain conditions can be used to produce zeros in the right-half plane.

  • Oscillations in nonlinear sampled-data systems

    Publication Year: 1963, Page(s):350 - 355
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1421 KB)

    In this paper a method is presented to examine the necessary conditions for the existence of certain limit cycles in nonlinear sampled-data systems. The method is based on the principle of specifying a certain repetitive output from the nonlinearity and finding under what conditions this sequence will be sustained. Many examples are worked to illustrate the method. View full abstract»

  • Complete and exact identification of self-sustained oscillations in relay sampled-data systems

    Publication Year: 1963, Page(s):355 - 363
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1818 KB)

    A simple and systematic approach is presented to obtain the complete, exact, and exhaustive description of limit cycles that may exist in a relay sampled-data control system. The final expression in its closed form is obtained by simple substitution. There is no restriction on the order of the plant, nor does the feedback have to be unity. The period of the oscillation poses no problem in the appr... View full abstract»

    This paper describes the experimental evaluation of the dynamic characteristics of an air-borne multipurpose gas turbine engine and its control components. Justification of the test technique is given and the test procedure and type of instrumentation used in the evaluation is discussed, as are the methods of generating the driving functions for the test. The results of the evaluation are presente... View full abstract»

  • A procedure for checking the real part of Z(jw) for nonnegativeness

    Publication Year: 1963, Page(s):375 - 377
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (761 KB)

    Checking Z(jw) for nonnegativeness reduces to an investigation of the behavior of the real part of the product of the pertinent V(jw) and the complex conjugate of I(jw). This real part function is constructed on the basis of piece-wise linearization of the voltage and current graphs and then reduced, using Tschebyscheff polynomials, to an equivalent ordinary polynomial which is tested for nonnegat...

    The second method of Liapunov is used to establish global asymptotic stability for certain nonlinear differential equations. On the basis of results obtained it is found that criteria, similar to the usua Routh-Hurwitz criteria for linear systems, can be established for rather general nonlinear systems. The results of other authors' investigations are discussed in view of the variable gradient met... View full abstract»

    PRESENT-DAY aircraft electric power distribution systems are complex and are used to transmit considerable amounts of power. These systems are becoming more complex and are being operated at higher power levels as the number of electrically operated aircraft instruments, controls, and auxiliary equipment increases. Large military surveillance aircraft, carrying powerful radar and electronic counte... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2535 KB)

    A completely static nuclear-powered thermoelectric generator is discussed. The reactor, designed for snap-10 (Systems for Nuclear Auxiliary Power), uses U235-zirconium-hydride fuel moderator and is capable of operating a thermoelectric generator at a hot-side temperature of 1,000 to 1,200 F (degrees Fahrenheit). A prototype thermoelectric generator is described which produced 250 watts of electric... View full abstract»
