Multiple Objective Co-Optimization Of Switched Reluctance Machine Design And Control, Timothy Burress
Doctoral Dissertations
This dissertation includes a review of various motor types, a motivation for selecting the switched reluctance motor (SRM) as a focus of this work, a review of SRM design and control optimization methods in literature, a proposed co-optimization approach, and empirical evaluations to validate the models and proposed co-optimization methods.
The switched reluctance motor (SRM) was chosen as a focus of research based on its low cost, easy manufacturability, moderate performance and efficiency, and its potential for improvement through advanced design and control optimization. After a review of SRM design and control optimization methods in the literature, it was found …
Design And Control Of Close Proximity Indirect Exposure For Nonthermal Atmospheric Pressure Plasma-Based Oxidation Of Carbon Fiber Precursor, Truman Andrew Bonds
Design And Control Of Close Proximity Indirect Exposure For Nonthermal Atmospheric Pressure Plasma-Based Oxidation Of Carbon Fiber Precursor, Truman Andrew Bonds
Doctoral Dissertations
A new plasma-based method for the stabilization of polyacrylonitrile carbon fiber precursor utilizing reactive chemical species derived from a custom atmospheric pressure plasma generation system was developed and demonstrated. As opposed to the conventional stabilization method of convective heating in air, plasma-based stabilization efficiently introduces oxidative reactive species that both diffuse through and react faster with the precursor filaments, resulting in a faster and more efficient process. This method was successfully demonstrated with a variety of precursor chemistries, grades and sizes. The development effort was entirely experimental, with successive processing devices designed and constructed to examine various aspects of the …
