  • 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...

  • 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...

  • 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...

  • 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...

  • Simplification of large linear systems using two-step iterative method

    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....

  • Team differential games and non-linear signal processing

    Creator:
    Bugnon, Francois J.
    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...

  • Nonlinear control of high performance aircraft

    Creator:
    Bean, Ronnie A.
    Abstract:
    This thesis presents the design of various controllers for a highly maneuverable, high performance aircraft, namely the modified F-18. The aircraft was required to perform high angle-of-attack maneuvers, for which the aircraft behaves in as a highly nonlinear system. An adaptive PID controller was used to control the aircraft through...

  • 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...
