Adaptive Output Feedback Control of Flexible Systems
(Georgia Institute of Technology, 2004-04-12)
Neural network-based adaptive output feedback approaches that augment a linear control design are described in this thesis, and emphasis is placed on their real-time implementation with flexible systems. Two different ...
Efficient Tools For Reliability Analysis Using Finite Mixture Distributions
(Georgia Institute of Technology, 2004-12-02)
The complexity of many failure mechanisms and variations in component manufacture often make standard probability distributions inadequate for reliability modeling. Finite mixture distributions provide the necessary ...
Acoustic radiation from premixed flames disturbed by turbulent velocity fluctuations
(Georgia Institute of Technology, 2004-06-07)
A Numerical Investigation on the Influence of Engine Shape and Mixing Processes on Wave Engine Performance
(Georgia Institute of Technology, 2005-01-12)
Wave engines are a class of unsteady, air-breathing propulsion devices that use an intermittent combustion process to generate thrust. The inherently simple mechanical design of the wave engine allows for a relatively low ...
Large Eddy Simulation of a High Aspect Ratio Combustor
(Georgia Institute of Technology, 2006-11-20)
The present research investigates the details of mixture preparation and combustion in a two-stroke, small-scale research engine with a numerical methodology based on large eddy simulation (LES) technique. A major motivation ...
Parameter-Dependent Lyapunov Functions and Stability Analysis of Linear Parameter-Dependent Dynamical Systems
(Georgia Institute of Technology, 2003-10-27)
The purpose of this thesis is to develop new stability conditions for several linear dynamic systems, including linear parameter-varying (LPV), time-delay systems (LPVTD), slow LPV systems, and parameter-dependent linear ...
A Multiscale Forecasting Methodology for Power Plant Fleet Management
(Georgia Institute of Technology, 2005-02-14)
In recent years the electric power industry has been challenged by a high level of uncertainty and volatility brought on by deregulation and globalization. A power producer must minimize the life cycle cost while meeting ...
Large Eddy Simulation of a Stagnation Point Reverse Flow Combustor
(Georgia Institute of Technology, 2006-08-17)
In this study, numerical simulations of a low emission lab-scale non-premixed combustor are conducted and analyzed. The objectives are to provide new insight into the physical phenomena in the SPRF (Stagnation Point Reverse ...
Simulations of a Sub-scale Liquid Rocket Engine: Transient Heat Transfer in a Real Gas Environment
(Georgia Institute of Technology, 2006-11-21)
The prediction of transient phenomena inside Liquid Rocket Engines (LREs) has not been feasible until now because of the many challenges posed by the operating conditions inside the combustion chamber. Especially, the ...
Numerical simulation of rotating stall and surge alleviation in axial compressors
