  • Analysis and control of power systems using orthogonal expansions

    Creator:
    Fernandes, Stephen Ronald
    Abstract:
    In recent years, considerable attention has been focused on the application of orthogonal expansions to system analysis, parameter identification, model reduction and control system design. However, little research has been done in applying their useful properties to Power System analysis and control. This research attempts to make some inroads in...

  • Bilinear stochastic processes and time series

    Creator:
    Tang, Zhigiang
    Abstract:
    In engineering, biology, ecology, medicine, economics and social science, some processes are essentially bilinear, and some could be approximated accurately by bilinear processes under certain conditions. In this thesis the bilinear stochastic process and bilinear time series are discussed. Bilinear models essentially are nonlinear; the superposition rule is not valid....

  • A model of the likelihood of stimulation or tolerance of the B lymphocyte

    Creator:
    Peterson, Patricia A.
    Abstract:
    The B lymphocyte is the immune cell responsible for the production of antibodies. It has receptor molecules on its surface which bind to a molecule known as an antigen. The antigen either stimulates the cell to produce antibodies or tolerizes it so that it is unable to produce antibodies. It...

  • Nonlinear neural control with power systems applications

    Creator:
    Chen, Dingguo
    Abstract:
    Extensive studies have been undertaken on the transient stability of large interconnected power systems with flexible ac transmission systems (FACTS) devices installed. Varieties of control methodologies have been proposed to stabilize the postfault system which would otherwise eventually lose stability without a proper control. Generally speaking, regular transient stability is...

  • Mathematical modeling and the control of immune processes with application to cancer

    Creator:
    Lee, Kwon Soon
    Abstract:
    A foundation for the control of tumors is presented, based upon the formulation of a realistic, knowledge-based mathematical model of the interaction between tumor cells and the immune system. The parametric control variables relevant to the latest experimental data, e.g., the sigmoidal dose-response relationship and Michaelis-Menten dynamics, are also considered....

  • Optimization of stochastic dynamic system with random coefficients

    Creator:
    Yi, Man Hyung
    Abstract:
    The problem of optimization of stochastic dynamic systems with random coefficients is discussed. Systems with both Wiener processes and uncertain random-process disturbances are dealt with in this dissertation, and these include certain bilinear stochastic systems. It is the purpose of this thesis to study the optimal control and, to some...

  • Nonlinear approach to the direction finding problem in array processing

    Creator:
    Ill-keun Rhee
    Abstract:
    In sonar or radar array processing, one of the most important objectives is to estimate the angles of incidence of distant source signals in a noisy environment. The standard eigenstructure-based method, which is known to yield high resolution spectral estimates for solving the direction finding problem, relies on the assumption...

  • An optimal control approximation for a certain class of nonlinear filtering problems

    Creator:
    Halawani, Talal Umar
    Abstract:
    A new approximation technique to a certain class of nonlinear filtering problems is considered in this dissertation. The method is based on an approximation of nonlinear, partially-observable systems by a stochastic control problem with fully observable state. The filter development proceeds from the assumption that the unobservables are conditionally Gaussian...

  • Restoration of quadratically distorted images

    Creator:
    Kwon, Tae-hwan
    Abstract:
    The problem of the restoration of quadratically distorted images is considered in this investigation, based upon the fact that images formed by partially coherent illuminations are related quadratically to the amplitude of the object. Two of the most important problems in image restoration are: 1) determining the degradation characteristics of...

    Abstract:
    In this thesis, A nonlinear methodology for the control of the highly maneuverable, high performance aircraft HARV (F-18) is studied by using sliding-mode control (SMC). This control law, which takes a continuous function when the input constraints are not considered, satisfies the reachability condition by which concerned states are driven...

    Creator:
    Shoji, Fumihiro Frank
    Abstract:
    The order of the practical system (e.g. nuclear power plants, electrical power network and chemical plant) is quite large. However, there are many limitations in computing facilities for the large system. Because of these limitations, it is often necessary to reduce the order of the large system using an approximation....

    Abstract:
    Team pursuit-evasion games are studied here with one performance index for the team as a unit in competition with one common opponent. Particular structures of team games are discussed after a brief introduction of the two-player differential games. The classical calculus of variations is used to derive the feedback strategies...

    Abstract:
    This thesis is composed of four parts: i) system description, ii) model development, iii) parameter estimation, and iv) validation. The natural system used here is an aspect of the immune system, namely, the distribution of recirculating lymphocytes in various organs throughout the body. This distribution gains importance because: i) it...

  • Observability and information structure of nonlinear systems

    Creator:
    Hwang, Chun Sik
    Abstract:
    An observability problem for both deterministic and stochastic systems is studied here. Deterministic observability is a determination of whether every state of the system is connected to the observation mechanism and how it is connected, if connected. On the other hand, stochastic observability discusses the "tightness" of the connection in...

  • Neural network control of nonlinear discrete time systems

    Abstract:
    The main focus of this work is on the problem of existence of nonlinear optimal controllers realizable by artificial neural networks. Theoretical justification, currently available for control applications of neural networks, is rather limited. For example, it is unclear which neural architectures are capable of performing which control tasks. This...
