  • Investigation of automatic construction of reactive controllers

    Creator:
    Westerberg, Caryl J.
    Abstract:
    In real-time control systems, the value of a control decision depends not only on the correctness of the decision but also on the time when that decision is available. Recent work in real-time decision making has used machine learning techniques to automatically construct reactive controllers, that is, controllers with little...

  • Supervisory control of a doubly-fed machine

    Creator:
    Werahera, Priya N.
    Abstract:
    An EMCON-D distributed process controller is evaluated for control and monitoring of an experimental doubly-fed machine system. A closed-loop control circuit is implemented to operate the doubly-fed machine with constant rotor current. A standard PID algorithm as well as an algorithm tailored to the doubly-fed machine are evaluated.

  • Design of a Biomass Feeding Robot for Controlled Cookstove Testing

    Creator:
    O'Boyle, Duncan
    Abstract:
    The purpose of this report is to detail the design and validation of a prototype robot that feeds biomass into a range of small household cookstoves at a programmable rate. Improved design and testing methods for the development of improved biomass cookstoves are needed to design stoves that alleviate the...

  • Model flexible assembly system

    Creator:
    Ho, Chi-Sung
    Abstract:
    Increasing automation and highly flexible manufacturing processes cause increasing complexity for manufacturing system. FMS (Flexible Manufacturing System) is an approach to solve this problem. Since the elements of the FMS and manufacturing process performance are closely interrelated, the application of simple modeling and emulation techniques in the planning stages for...

  • A programmable system scheduler for control oriented local area networks (COLAN)

    Creator:
    Lim, Choo-chiang
    Abstract:
    The Control-Oriented Local Area Network (COLAN) is a distributed control system for a series of networked microcontrollers, which has been under development at Oregon State University since 1986. A reliable master controller, functioning both as a task scheduler and as a network controller, is required to allow users to perform...

  • Direct torque control for brushless doubly-fed machines

    Creator:
    Brassfield, William R.
    Abstract:
    The Brushless Doubly-Fed Machine (BDFM) has recently become an important research topic in the field of variable-speed AC drives. In recent studies, the BDFM has shown significant potential for improving the reliability and performance of AC drive systems, as well as reducing total system cost. While the BDFM offers several...

  • Proportional integral derivative control of an oil-heated fractal-like branching microchannel desorber

    Creator:
    Davis, Keith R.
    Abstract:
    A PID controller was designed to control the performance of an oil-heated fractal-like branching microchannel desorber for use in an ammonia-absorption refrigeration system. Both the amount and concentration of ammonia refrigerant generated at the desorber can be controlled by choosing the rectified circulation ratio as the controlled variable in a...

  • 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...

  • The MiniSpec : a low-cost, compact, FPGA-based gamma spectrometer for mobile applications

    Creator:
    Becker, Eric M.
    Abstract:
    There is a significant role in emergency response and personal radiation safety that can be played by a compact radiation detector that is capable of identifying radionuclides. Herein is described the design, construction, and characterization of a small, low-cost, low-power gamma ray spectrometer prototype intended to fill this role, conducted...

  • Development test suite for FPGA TekBot learning platform

    Creator:
    Lai, Gerald
    Abstract:
    As the Tekbots program expands into senior and graduate level classes at Oregon State University, so does the need arise for more complex learning platforms. These complex hardware platforms cannot be adequately tested in a manufacturing environment as we have done previously. Also, due to their complexity, these platforms require...
