  • Real time predictive control of generating system using hybrid computer and a fast time adaptive model

    Creator:
    Heuch, Knut
    Abstract:
    A system consisting of two d-c generators, one exiting the other, is controlled with an EAI 690 hybrid computer in an on-line operation. The hybrid computer works as a predictive controller with an on-off actuating signal. A fast-time, second-order model is used to determine the switching time, and a small...

  • Real-time predictive voltage control of a direct-current generating system, using a hybrid computer

    Creator:
    Nehrir, Mohammad Hashem
    Abstract:
    Real-time predictive voltage control of a direct-current (d-c) generating system is achieved with the aid of a hybrid computer. Some assumptions were required to adequately simplify the simulation of the d-c generating system. A predictive controller is used to maintain the load voltage of the d-c generating system (the controlled...

  • Direct digital speed control system for a DC motor using a minicomputer

    Creator:
    Evans, Donald LeRoy
    Abstract:
    Direct digital control is becoming quite common in the control of industrial processes. However, due to the relatively high accuracy of both analog and conventional digital systems for controlling the speed of a dc motor, there has been a reluctance to try DDC for this purpose. This thesis describes a...

  • A low cost AC motor drive for battery powered applications

    Creator:
    Wiley, Brian
    Abstract:
    Environmental concerns have renewed the interest in electric vehicles. To gain widespread use, electric vehicles will also have to offer good performance and be reasonably priced. AC drive systems using modern semiconductors can provide efficient operation at the required power levels, but their cost at present is still too high....

  • Performance and parameter prediction of large synchronous machines from physical dimensions

    Creator:
    Heberle, David D.
    Abstract:
    A project funded by the Southern California Edison (SCE) Company, Research Center of Irwindale, California, has supported the development of a performance and parameter prediction software program for use during the refurbishment of large synchronous machines, turbine generators, and synchronous condensers. The computer program was developed for SCE to allow...

  • Hardware design and protection issues in an AC/AC converter

    Creator:
    Faveluke, Alex
    Abstract:
    An AC/AC converter has been designed and implemented for the purpose of providing a modular drive system with a Brushless Doubly-Fed Machine (BDFM.) This converter is to be used in laboratory testing and also as part of a demonstration system in the field. All hardware needed to start and run...

  • Novel control of a permanent magnet linear generator for ocean wave energy applications

    Creator:
    VanderMeulen, Aaron H.
    Abstract:
    Wave energy conversion devices are a rapidly growing interest worldwide for the potential to harness a sustainable and renewable energy source. Due to the oscillatory nature of ocean waves, the power generated from a permanent magnet linear generator (PMLG) for ocean wave energy conversion is pulsed. Focusing on direct drive...
