  • Reliable controller design for systems with transients

    Creator:
    Feng, Lei
    Abstract:
    Reliable controller designs have been developed in this thesis for a number of finite-horizon and infinite-horizon problems with possibly non-zero initial conditions. These reliable controllers assure that system stability and system performance will be maintained despite certain system faults. The performance measure used in this thesis is an "H[subscript ∞]-like...

  • Design of high-speed low-power analog CMOS decision feedback equalizers

    Creator:
    Su, Wenjun
    Abstract:
    Decision feedback equalizer (DFE) is an effective method to remove inter-symbol interference (ISI) from a disk-drive read channel. Analog IC implementations of DFE potentially offers higher speed, smaller die area, and lower power consumption when compared to their digital counterparts. Most of the available DFE equalizers were realized by using...

  • Design of high-speed adaptive parallel multi-level decision feedback equalizer

    Creator:
    Xiang, Yihai
    Abstract:
    Multi-level decision feedback equalization (MDFE) is an effective technique to remove inter-symbol interference (ISI) from disk readback signals, which uses the simple architecture of decision feedback equalization. Parallelism which doubles the symbol rate can be realized by setting the first tap of the feedback filter to zero. A mixed-signal implementation...

  • Design of high-speed summing circuitry and comparator for adaptive parallel multi-level decision feedback equalization

    Creator:
    Gao, Hairong
    Abstract:
    Multi-level decision feedback equalization (MDFE) is an effective sampled signal processing technique to remove inter-symbol interference (ISI) from disk read-back signals. Parallelism which doubles the symbol rate can be realized by utilizing the characteristic of channel response and decision feedback equalization algorithm. A mixed-signal IC implementation has been chosen for...

  • Adaptive methods for robust commercial vehicle control

    Creator:
    Junell, Jaime L.
    Abstract:
    This thesis explores the implementation of learning based control with predictive cruise control and the potential this technology has for increasing fuel efficiency while keeping on a well maintained schedule for commercial trucks. Traditional cruise control is wasteful when maintaining a constant velocity over rolling hills. Predictive cruise control is...

  • Ultra-low energy digital logic controller design for wireless sensor networks

    Creator:
    Meliza, Stephen W.
    Abstract:
    Low energy design techniques for digital circuits are examined to determine their suitability for use in a digital logic controller for wireless sensor network nodes. Transistor level simulations are used to evaluate the techniques and those demonstrating an energy reduction are used to implement a digital logic controller. The digital...

  • Comparison of two microvalve designs fabricated in mild steel using microprojection welding and capacitive dissociation

    Creator:
    Terhaar, Tyson J.
    Abstract:
    Since the dawn of the computer age, there has been a push to create miniature devices. These devices were initially integrated circuit (IC) devices to perform calculations for computers. As the technology progressed, the scope of the devices diverged to included microelectromechanical (MEMS) devices, meaning that the devices perform mechanical...

  • Detecting fluid flows with bioinspired hair sensors

    Creator:
    Dickinson, Benjamin T.
    Abstract:
    Many animals detect prey or enhance their locomotion with information from hair-like receptors that are activated by local fluid flows. The utility of biological hair receptors has motivated the design of artificial hair sensors (AHS) for flow control applications where aerodynamic or hydrodynamic forces play a significant role in the...

  • Industrial power system faults

    Creator:
    Badr, Ahmad Mohamad Amin
    Abstract:
    The purpose of this thesis is to represent and calculate unsymmetrical secondary faults on a grounded wye-to-delta transformer bank. This thesis is specifically concerned with the secondary connections often encountered in industrial installations. Faults on these systems have not been adequately investigated. Three types of faults are considered, namely: 1....

  • The use of electrochemical micromachining for making a microfloat valve

    Creator:
    Park, Sang-Bin
    Abstract:
    Micromanufacturing consists of processes for producing structures, devices or systems with feature sizes measured in micrometers. Micromanufacturing began in the mid-1960's with microelectronics fabrication technology. In the 1980's, Micro-Electro-Mechanical Systems (MEMS) began to be developed, in which electrical and mechanical subsystems were integrated at small scales. More recently, Microtechnology-based Energy...
