  • Drain current transient characterization of P-channel GaAs MESFET

    Creator:
    Peng, Lan L.
    Abstract:
    GaAs MESFETs are widely used in high speed integrated circuits (ICs) and microwave circuits. Due to the materials and processing methods used in GaAs MESFET fabrication, deep level traps in the substrate materials have a strong influence on device performance. In this work we used the drain current transient characterization...

  • An adaptive pitch axis autopilot design for an unstable nonminimum phase pitch axis model

    Creator:
    Chen, Long Ren
    Abstract:
    An adaptive pitch axis autopilot design procedure is presented. The design procedure is applicable to both stable and unstable pitch axis models and to those having nonminimum phase. The design approach assumes the adaptive autopilot is activated after achieving level flight. It is shown a rate-feedback compensator can be designed...

  • Critical evaluation of Ouyang's model reduction method

    Creator:
    Jia, Zuxin
    Abstract:
    A model reduction method for stable, linear, time-invariant, continuous systems is critically studied. This method, proposed by Prof. Ouyang, is based on the concept of power dispersion and the least-squared estimation technique. The reduced models obtained by this method retain the stability of the stable, high order original systems and...

  • A study of time series interpolation and decimation with signal processing applications

    Creator:
    Kraemer, Thomas Fredrick
    Abstract:
    Decimation and interpolation is shown to be an effective technique for reducing the storage requirements for bandlimited time series. Interpolation and decimation is theoretically developed using z-transform theory and graphically interperted. A sequence of data acquired by sampling a sonar signal is used to demonstrate the effects of decimation. Using...

  • A method for controlling and stabilizing the pitch-axis dynamics of a magnetically levitated train

    Creator:
    Ramchandran, Ashok
    Abstract:
    An electro-dynamic Magnetic Levitation vehicular system has been modelled and studied. In practice, a MagLev vehicle will consist of a number of cars which are mechanically coupled to each other. It is reasonable to assume that each of these cars will be independently controlled with the help of a supervisory...

  • Evaluation of a pole placement controller for a planar manipulator

    Creator:
    Doustmohammadi, Ali
    Abstract:
    The effectiveness of linear control of a planar manipulator is presented for robot operation markedly exceeding the limits of linearity assumed in the design of the linear controller. Wolovich's frequency domain pole placement algorithm is utilized to derive the linear controller. The control scheme must include state estimation since only...

  • A model for the generation and study of electromyographic signals

    Creator:
    Lerman, David
    Abstract:
    A computer model simulating the electrical activity of muscles of the upper arm during elbow motion is presented. The output of the model is an Electromyographic (EMG) signal. System identification is performed on the EMG signals using autoregressive moving average (ARMA) modelling. The calculated ARMA coefficients are then used as...

  • Characterization of solution-based inorganic semiconductor and dielectric materials for inkjet printed electronics

    Creator:
    Munsee, Craig L.
    Abstract:
    The long-term goal of this research project is the development of solution-based inorganic dielectric and semiconductor materials for inkjet printed electronics. The main focus of this thesis involves testing of the materials and devices under development. A new solution-based inorganic dielectric material (HfOSO₄), given the name hafsox, is developed and...

  • Development, fabrication, and characterization of transparent electronic devices

    Creator:
    Hoffman, Randy L.
    Abstract:
    The objective of this thesis is to provide an initial demonstration of the feasibility of constructing highly transparent active electronic devices. Such a demonstration is successfully achieved in the fabrication of ZnO-based thin film transistors (TFTs) exhibiting transparency greater than ~90% in the visible portion of the electromagnetic spectrum and...
