Automatic Development And Adaptation Of Concise Nonlinear Models For System Identification, William G. La Cava
Automatic Development And Adaptation Of Concise Nonlinear Models For System Identification, William G. La Cava
Doctoral Dissertations
Mathematical descriptions of natural and man-made processes are the bedrock of science, used by humans to understand, estimate, predict and control the natural and built world around them. The goal of system identification is to enable the inference of mathematical descriptions of the true behavior and dynamics of processes from their measured observations. The crux of this task is the identification of the dynamic model form (topology) in addition to its parameters. Model structures must be concise to offer insight to the user about the process in question. To that end, this dissertation proposes three methods to improve the ability …
Lattice Boltzmann Methods For Wind Energy Analysis, Stephen Lloyd Wood
Lattice Boltzmann Methods For Wind Energy Analysis, Stephen Lloyd Wood
Doctoral Dissertations
An estimate of the United States wind potential conducted in 2011 found that the energy available at an altitude of 80 meters is approximately triple the wind energy available 50 meters above ground. In 2012, 43% of all new electricity generation installed in the U.S. (13.1 GW) came from wind power. The majority of this power, 79%, comes from large utility scale turbines that are being manufactured at unprecedented sizes. Existing wind plants operate with a capacity factor of only approximately 30%. Measurements have shown that the turbulent wake of a turbine persists for many rotor diameters, inducing increased vibration …
