Ph.D. Students

Nathan Weir: Precision Motion Control
My research focuses on the development of precision motion control strategies for inertially stabilized pointing systems. Precision pointing systems are used to aim and stabilize sensitive instrument or sensor payloads for a variety of applications including photography, videography, astronomy, remote sensing, and communications. The jitter requirements for future systems grow more demanding as higher resolution sensors become available. Pointing systems that require a large field of regard and high precision are often limited in performance with conventional bearing technologies. This research seeks to advance the state of the art of precision stabilization systems through the design, analysis, and experimental evaluation of a novel hybrid flexure bearing concept to minimize the effects of nonlinear friction that typically degrade jitter performance in systems with conventional ball bearing joints.

Oyuna Angatkina: Thermosys Improvements
headshot My current research is about making Thermosys more user-friendly. In the Fall semester I worked on the thermostatic expansion valve model to better align the model parameters with information available on manufacturer data sheets.

Ashley Armstrong: Dynamic Modeling and Control of a Micro Robotic Deposition System
Dynamic modeling and control of a Micro Robotic Deposition System, with bone scaffold manufacturing as the target application. In this research, precision motion control techniques will be explored to achieve the high levels of precision and response time demanded by microscale applications. Movement coordination between two additive manufacturing extrusion heads will be used to print bone scaffolds with advanced architecture.

Pamela Tannous: Electrical Thermal Power Systems
My current research is sensors placement and optimization. High temperature has negative effects on the lifetime and the efficiency of electronic components. This research objective is to decide on the minimum number and placement of temperature sensors needed in order to estimate the temperature distribution of an inverter so that the highest temperature of the board can be maintained below a certain specific temperature.

Spencer Igram: Additive Manufacturing and Optimization of Superparamagnetic Electronics Components
Profile - Spencer Igram

    My current work aims to create a new class of novel inductors and related passive devices from superparamagnetic nanomaterials. Specially formulated to maintain magnetic properties, we extrude the nanoparticles in an expoy substrate using additive manufacturing techniques similar to microRobotic Deposition for fast prototyping and development as opposed to common molding methods.

Christopher Aksland: Control and Optimization of Electro-Thermal Power Systems
My research focuses on the modeling of electro-thermal systems and components such as batteries and battery packs. The performance of batteries is closely related to their operating temperature; if a battery is to hot, its lifetime degrades. By modeling these components and integrating them with HVAC components, we can better understand and control a variety of power systems, such as those that exist in HEVs.

M.S. Students


Cary Laird: Electrical/Thermal Power Systems

    My research focuses on improving the pulsed power capabilities of current energy storage systems by combining battery packs with supercapacitors. By modeling these hybrid energy storage systems (HESS), we can demonstrate improved power capabilities and battery life.

Mindy Wagenmaker: Electrical/Thermal Power Systems

    As the trend towards electrification continues, improving thermal management control has become an important consideration in designing reliable systems. My current research is to understand and build models of electrical-thermal systems so that we can simulate how they would respond to a controller. This will benefit our research process as it allows us to run simulations and quickly determine how our systems interact when they’re coupled and in which controllers would be suitable, before actually running time-consuming experimental tests.
