The Use Of The Fast Hankel Transform For Sound Radiation Calculations With Application To The Prediction Of Sound Radiation From An Arbitrarily Positioned Multipole Placed Near A Plane Reflecting Surface, Zqiang Hu, J Stuart Bolton Jan 1992

The Use Of The Fast Hankel Transform For Sound Radiation Calculations With Application To The Prediction Of Sound Radiation From An Arbitrarily Positioned Multipole Placed Near A Plane Reflecting Surface, Zqiang Hu, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

In a recent paper the authors described the use of a finite, two-dimensional discrete Hankel transform to predict the sound radiation from multipole sources placed near reflecting surfaces. When using that technique, the wavenumber spectrum of the incident sound field is first defined either numerically or analytically. The incident wavenumber spectrum is then combined with the reflection coefficient of the surface to yield the wavenumber spectrum of the reflected field which can then be added to the incident field and the result inverse transformed to give the spatial distribution of the sound pressure. In principle that technique may be used …

Methodologies For Voltage Contingency Ranking, James Matthew Kulaga Dec 1991

Methodologies For Voltage Contingency Ranking, James Matthew Kulaga

Department of Electrical and Computer Engineering Technical Reports

Contingency studies in interconnected electric power systems are performed to assess the capability of a system to withstand disturbances caused by equipment outages and other factors, and are relevant to the area of power system security. Due to the large size and complexity of modern power systems, accurate techniques for measuring the effect of line contingencies are often time consuming and impose a heavy computational burden. Thus, ranking methods are used to define a subset of the most severe contingencies to be studied in full detail. Contingencies are classified into voltage contingencies and power contingencies; the term voltage contingency refers …

Minimizing Quotient Space Norms Using Penalty Functions, Stefen Hui, Walter E. Lillo, Stanislaw H. Zak Nov 1991

Minimizing Quotient Space Norms Using Penalty Functions, Stefen Hui, Walter E. Lillo, Stanislaw H. Zak

Department of Electrical and Computer Engineering Technical Reports

A penalty function method approach is proposed to solve the general problem of quotient space norms minimization. A new class of penalty functions is introduced which allows one to transform constrained optimization problems of quotient space norms minimization by unconstrained optimization problems. The sharp bound on the weight parameter is given for which constrained and unconstrained problems are equivalent. Also a computationally efficient bound on the weight parameter is given. Numerical examples and computer simulations illustrate the results obtained.

Output Feedback Variable Structure Controllers And State Estimators For Uncertain Dynamic Systems, Stanislaw H. Zak, Stefen Hui Nov 1991

Output Feedback Variable Structure Controllers And State Estimators For Uncertain Dynamic Systems, Stanislaw H. Zak, Stefen Hui

Department of Electrical and Computer Engineering Technical Reports

In this paper we propose a new class of output feedback variable structure controllers and state estimators (observers) for uncertain dynamic systems with hounded uncertainties. No statistical information about the uncertain elements is assumed. A variable structure systems (VSS) approach together with the geometric approach to the analysis and synthesis of system zeros are employed in the synthesis of the proposed output feedback controllers and state estimators. The role of system zeros in the output feedback stabilization and state estimation, using the VSS approach, is discussed. Numerical examples included illustrate the feasibility of the proposed stabilization and state estimation schemes.


Neural Networks For Constrained Optimization Problems, Walter E. Lillo, Stefen Hui, Stanislaw H. Zak Nov 1991

Neural Networks For Constrained Optimization Problems, Walter E. Lillo, Stefen Hui, Stanislaw H. Zak

Department of Electrical and Computer Engineering Technical Reports

This paper is concerned with utilizing neural networks and analog circuits to solve constrained optimization problems. A novel neural network architecture is proposed for solving a class of nonlinear programming problems. The proposed neural network, or more precisely a physically realizable approximation, is then used to solve minimum norm problems subject to linear constraints. Minimum norm problems have many applications in various areas, but we focus on their applications to the control of discrete dynamic processes. The applicability of the proposed neural network is demonstrated on numerical examples.
