    Short-circuit currents, which are particularly high on ships, result from the combined contribution of generators and motors. This phenomenon can be analyzed with equations expressing the transient conditions of 3-phase rotating machines. Some simplification of these equations allows an easy calculation of short-circuit currents; however, tests are necessary to determine accurate maximum peak and ... View full abstract»

    The stability of certain discontinuous feedback systems is analyzed by using the z-transform theory. In the z plane, a system which is equivalent to the nonlinear system under steady-state conditions can be found, as well as the existence of any limit cycle, together with the frequency at which it occurs. An intuitive argument for the stability of a limit cycle is also presented, several examples ... View full abstract»

  • Reverse Generator Voltage with Unidirectional Trinistor Control Rectifier

    Publication Year: 1964, Page(s):372 - 377
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1063 KB)

    Most metal mill drives use separate d-c generators for accurate speed control. Generator voltage and motor speed is controlled by an unidirectional trinistor control rectifier which supplies excitation to the generator main field. To reverse the drive, generator voltage must be reversed either by using a bias field or by connecting the trinistor in buck-boost across the single-machine field. In ei... View full abstract»

  • The Effect of Rectifier Discontinuous Current on Motor Performance

    Rectifier performance with the low-inductance counter electromotive force (emf) load of a large d-c motor may be some-what different than the more conventional performance resulting from a highly inductive load. If, at low average values, the current is not continuous but flows in pulses, both the static and the dynamic characteristics of the rectifier-motor system are affected. In the case of a m...

    The no-load speed as a function of coil insertion slot opening and rotor skew is analyzed by operating directly on the flux density function of the stator for the 1-coil-per-pole motor. In addition, the no-load speed dependence on nonsinusoidal current excitation is derived. An attempt is made to note the effect of a skewed rotor which has been smeared by a manufacturing process. The maximum elect... View full abstract»

    This paper is concerned with the design of an electrohydraulic automatic gage control for a hot strip mill finishing train. The roll force method of gage control is employed wherein a measurement of the total force exerted by the mill upon the strip is used as an in-line variable to adjust the roll opening. Movement of the rolls is accomplished by energizing a hydraulic actuator mechanically conne... View full abstract»

    It will be shown that, for a single Gaussian noise source, an arbitrary number of mutually uncorrelated outputs can be produced by passing the noise through a parallel cascade of zero-memory nonlinear filters, where the output of the kth filter is related to its input by a kth-degree Hermite polynomial. This generalizes a recent finding<sup>1</sup> in which four noncorrelated outputs w... View full abstract»

    A linear system is completely controllable if for any initial state a control can be found to take the state of the system to the origin of the state space. Present criteria for testing linear systems for controllability require knowing the weighting function matrix of the linear system. In this paper a new criterion is presented which is applicable to a broad class of linear systems defined by li... View full abstract»

    This paper defines and summarizes several concepts and tools which have been developed to aid in the analysis of electronic systems from the part level through the system level. The problems explored are those for which the parameters, failure rates, and repair rates may be assumed constant; i.e., the exponential distribution may be assumed. It also is assumed that all parts, components, etc., are... View full abstract»

    A significant improvement in the miniaturization of an a-c to d-c power supply has been achieved by a circuit which combines pulse-amplitude and pulse-duration modulation to provide constant area pulses. The modulation is obtained in an inverter-regulator circuit which employs a saturating 2-core high-frequency transformer and gate turn-off semiconductor switches. The principal contributions to mi...

    This paper examines the behavior of 2-channel adaptive control systems, and shows that, contrary to elementary considerations, adjustment will not proceed generally along the line of steepest descent. Design criteria for multichannel adaptive systems are discussed and the conclusion reached that simultaneous adjustment of six variables is practicable. View full abstract»
