  • Extension of the optimum design through digital compensation for linear multivariable samplcd-data control systems

    Publication Year: 1962, Page(s):253 - 255

    Sampled-data control systems for linear multivariable plants subjected to disturbing signals are considered. The regulator problem (rejection of effects of disturbing signals in the outputs without taking into consideration command-output transfer functions) is treated first. Then the servo problem (rejection of disturbances and realization of a desired over-all transfer function) is treated as an... View full abstract»

  • An integral square self-optimalyzing adaptive control

    Publication Year: 1962, Page(s):256 - 262

    A digital adaptive control is introduced to maintain an optimal transient response in a minimum integral square sense without any perturbation required. The principal features of the control are discussed, and an analysis of some of the principal error sources is presented. View full abstract»

    This paper gives experimental and calculated speed-torque-current curves for a slip-ring induction motor with an automatically controlled secondary impedance to obtain stepless starting with low current, high sustained torque, and low full-load slip. A saturable reactor in the secondary circuit is supplied with a control current from a direct-connected exciter on the motor shaft. Since the control... View full abstract»

  • Wide-range reversible voltage controllers for polyphase induction motors

    Publication Year: 1962, Page(s):272 - 277
    Cited by:  Papers (2)

    The many static, magnetic voltage controllers reported in the literature are shown to be combinations of four basic saturable reactor and saturable transformer connections. It is found that the replacement of series-connected saturable reactors by pairs of back-to-back connected silicon-controlled rectifiers is feasible in some control applications, thus providing opportunities for more compact, m...

  • Improving the linearity of the steady-state gain characteristic by use of nonlinear feedback

    Publication Year: 1962, Page(s):277 - 282
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1265 KB)

    The problem of linearizing the over-all response of a device with a nonlinear gain characteristic (mainly of the saturation type) is solved by using nonlinear feedback. The nonlinear curve is approximated by an exponential which has the advantage of matching the over-all response for two conditions. To the extent that the actual gain is exactly equal to a portion of an exponential curve, the devic... View full abstract»

  • A method of determining the transfer function of a linear system in terms of its pol es and zeros from the frequency response

    Publication Year: 1962, Page(s):282 - 290

    A procedure is developed for obtaining the transfer function of a linear system from the frequency-response data in terms of its poles and zeros. The method is based upon the fact that the transfer function is an analytic function of the complex variable s at all points in the s plane except the isolated points which are the poles of the function. Hence if the function is specified along the j¿ a... View full abstract»

  • Design of lead networks for A-C servos with carrier-frequency drift

    Publication Year: 1962, Page(s):291 - 296
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1151 KB)

    In a-c servomechanisms tandem compensation is effected by the use of a-c notch-type networks, which operate on the modulating envelope by virtue of being resonant at, and sufficiently symmetrical around, the carrier frequency. However, if carrier frequency drifts away from the notch, the two sidebands of suppressed-carrier-modulated signal around it are no longer symmetrical. The adverse effects o... View full abstract»

  • Silicon rectifier cells for power rectification on railway vehicles

    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (8560 KB)

    Application and tests on a silicon power rectifier installed on an existing multiple-unit passenger car in place of the original ignitron rectifier permitted evaluation of silicon rectifiers in traction propulsion power service and proved their feasibility in actual field operation. Both static tests and actual service tests showed that the equipment was satisfactory for extended field testing, wh... View full abstract»

  • Voltage regulation of D-C power supply with suddenly applied load

    Publication Year: 1962, Page(s):305 - 309

    A method to obtain the voltage regulation of 6-phase and 12-phase double-way transformer rectifiers is presented. After determining the generator load power factor due to the transformer rectifier, a means of finding the generator voltage regulation is described. The algebraic sum of these two voltage regulations is then the voltage regulation of the power supply with suddenly applied load. View full abstract»

  • Generalized theory of the thermionic plasma energy converter

    Basic principles of thermionic emission, ion generation and plasma properties are used to examine a model of the vapor-filled thermionic plasma energy converter. The model divides the converter's interelectrode space into plasma, emitter, and collector sheath regions. At least seven main equations evolve from consideration of these three regions, namely, current, charge, plasma ion, plasma energy,... View full abstract»
