  • Synthesis of quasi-stationary optimum nonlinear control systems: Part I ¿¿ Synthesis considerations

    Publication Year: 1962, Page(s):313 - 319

    TYPE I SYSTEMS are defined as systems that give optimum time response (i.e., that reduce system error and its derivatives to zero in minimum time) by using maximum control effort. The number of torque reversals was shown by Bogner1 to be (n ¿¿ 1) for nth-order systems whose characteristic roots are all real and distinct and whose initial conditions are on the switching surface. The switching crite... View full abstract»

  • Synthesis of quasi-stationary optimum nonlinear control systems: Part II ¿¿ Extensions in mechanization concepts

    FOR OPTIMUM ¿¿bang-bang¿¿ or relaytype control systems of order higher than the second, there is the practical mechanization problem of requiring high-order function generators in realizing the system. For example, for t h e thirdorder system it appears that a function generator is required whose output is a function of two variables. Such a function generator is fairly complicated and expensive. ... View full abstract»

  • An introduction to Lyapunov's second method

    Publication Year: 1962, Page(s):325 - 332

    A general procedure for investigating stability of many sorts of dynamic systems is the second method of Lyapunov, which uses only the form of equations describing the system, without requiring explicit knowledge of their solutions. Its application to a given system requires determination of a special Lyapunov function which, for a stable system, is itself positive but has a negative time-derivati... View full abstract»

  • Design of noninteracting control systems using bode diagrams

    Publication Year: 1962, Page(s):336 - 346

    A systematic design procedure has been developed for noninteracting control of multivariable systems. Unlike previously proposed design techniques, which are mostly based on closed-loop complex-frequency transfer functions, the method described here is based on open-loop real-frequency Bode diagrams ¿ with the advantage that considerations of control specifications, physical realizability, and st...

  • Shading coil magnet of new design

    A reliable analytical method of new design of shading coil magnets is described. In the magnets of new design, with equal shaded and unshaded pole-face areas, the fluxes of the shaded and unshaded poles are made equal in magnitude with substantially sinusoidal time variation. The phase angle between the two fluxes can be made to exceed 80 degrees so that the minimum of the variable holding force i... View full abstract»

  • Analysis of the shading coil magnet

    THE MAGNETIC FORCE of attraction on the armature of a shading coil magnet varies at double the frequency of the impressed voltage. A chattering noise begins when an externally applied force, tending to pull the armature away, increases to the point where it is about equal to the minimum value of the variable magnetic force. The main purpose of this paper is to develop a simple method of design tha... View full abstract»

  • Digital computer analysis of closed-loop systems using the number series approach

    Publication Year: 1962, Page(s):370 - 378

    THE DEVELOPMENT of the high-speed digital computer is causing a revision of rather rigidly held concepts. For instance, it is possible to simulate completely an analog computer1 on a large-scale digital computer and achieve not only an increase in solution accuracy, but an improvement in solution speed. On the very large machines, also, one may increase the problem size beyond that possible in mos... View full abstract»

  • A self-adaptive system with a variable-parameter PID controller

    Publication Year: 1962, Page(s):378 - 386
    Cited by:  Papers (2)

    A new type of self-adaptive system has been developed in which parameters of the proportional-integral-differential (PID) controller are so selected that the controller may compensate the process dynamics, which is measured automatically and continuously. In this way, the total system dynamics is always near the ideal, even if the process dynamics changes in an unexpected way. View full abstract»

  • Electrical characteristics of electrochemical cell lines

    Publication Year: 1962, Page(s):387 - 394
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4930 KB)

    THE PURPOSE of this paper is to report the electrical characteristics of electrochemical cell lines, partly based on tests made on various types and ratings of cell lines, so that there will be a clearer understanding in the application of electric equipment. It includes a brief description of different types of cells, their start-up procedures, and mode of operation, as well some guides in the ap... View full abstract»

    A study has been made of a refractory metal-anode mercury-pool switch tube for transferring energy from capacitor banks to experimental apparatus for producing electron-ion plasma, pulsed magnetic fields and other applications. One of the special-purpose applications for these tubes is transferring stored energy from capacitor banks to experimental thermonuclear-fusion devices. In this application... View full abstract»

  • Magneto-thermionic power generation

    Publication Year: 1962, Page(s):398 - 403

    A design concept is presented which, under certain conditions, improves the efficiency of thermionic generators. The proposed concept envisages the application of a magnetic field perpendicular to the electrode surface. This applied field counteracts the adverse effect of the self-induced transverse magnetic fields present in large thermionic generators. In addition, the applied magnetic field may...
