Adaptive output feedback control of nonlinear systems
Zhu, Yongliang (2004-12) -
Design and analysis of feedback and feedforward control systems for web tension in roll-to-roll manufacturing
Raul, Pramod Rajaram (2015-05)In Roll-to-Roll (R2R) manufacturing, efficient transport of flexible materials (webs) on rollers requires simultaneous control of web speed and tension. Webs experience disturbing forces during transport due to nonideal ... -
Disk drive actuator design and control for robust non-operational shock performance
Ratliff, Ryan Todd (2005-12)As disk drives become more of a commodity based product, quality and cost control have become top industry priorities. Disk drive manufacturers are now heavily focused on efforts to reduce costs while maintaining quality ... -
Effects of ion irradiation on the mechanical properties and structural evolution of sol-gel derived hybrid silicate thin films
Qi, Yongli (2015-07)A study of the effects of ion irradiation on the surface mechanical properties and structural evolution of sol-gel derived hybrid silicate thin films has been conducted. Green films were synthesized through a sol-gel process ... -
Modeling and control of a permanently magnetized sphere's motion by field manipulation
Duvall, Matthew Glenn (2006-12)A model describing the motion of a magnetized sphere in a fluid medium subject to an applied field is developed. The inspiration for this system is rooted in technologies and procedures being explored in the biomedical ... -
Modeling and control of transport behavior of moving webs through heat transfer processes
Lu, Youwei (2015-07)Heat transfer processes are widely employed in Roll-to-Roll (R2R) process machines to heat/cool moving webs. The general goal is to efficiently transport webs over heating/cooling rollers and ovens while achieving the ... -
Modeling and control of web transport in the presence of non-ideal rollers
Branca, Carlo (2013-05)In roll-to-roll processes the presence of non-ideal elements, such us out-of-round or eccentric rollers is fairly common. Periodic oscillations in web tension and web velocity are observed because of the presence of such ... -
Modeling and optimization of Chemical Mechanical Planarization (CMP) using neural networks, ANFIS and evolutionary algorithms
Lih, Wen-Chen (2006-05)Scope and Method of Study: The purpose of this study is to provide new approaches to improve the current modeling and optimization of the chemical mechanical planarization or polishing (CMP) process. Neural Networks (NN), ... -
Modeling the effects of belt compliance, backlash, and slip on web tension and new methods for decentralized control of web processing lines
Dwivedula, Ramamurthy V. (2005-12)Scope and Method of Study: Non-ideal behavior of web process lines and new methods for regulation of web tension and web velocity are investigated. The non-ideal behavior considered includes the compliance and backlash in ... -
Modeling, analysis and control of print registration in roll-to-roll printing presses
Seshadri, Aravind (2013-05)Print registration in roll-to-roll (R2R) printing process is investigated in this dissertation. Print registration is the process of aligning multiple images that are printed in consecutive print units. The quality of the ... -
New techniques for clustering, selection of number of histogram bins, and estimation of quantiles of pairwise distances
Lolla, Sai Venu Gopal (2011-12)The emulation of Gestalt Laws was required for a proposed knowledge-based inference driven vision system. Emulating the Proximity gestalt law required a clustering technique that worked without: (a) the need for any input ... -
Robust vibration suppression control profile generation
Zhou, Li (2005-05)Scope and Method of Study:
