Dr. Bryan Rasmussen, Associate Professor

Current Members

Chao Wang

Education: Bachelor’s degree in Thermal Energy and Power Engineering from Chongqing University, Chongqing, China in 2008 and Master’s degree in Power Engineering from Zhejiang University, Hangzhou, China in 2011

Research Interests: He joined the group in September 2012 and is working on Heat Pump Dynamic Simulation and Control.

Christopher Bay

Education: University of Colorado Boulder - BS/MS Mechanical Engineering

Research Interests: Currently I am working on developing the necessary code to implement a DMPC method on Texas A&M's campus to provide more efficient control of the heating, cooling, and ventilation systems while maintaining user comfort. Also investigating different communication hierarchies of the DMPC method and their performance. Additionally, I help supervise two undergraduate teams working to develop a UAV platform that can perform automated energy audits of commercial and industrial buildings, providing the customer with an energy audit report and an energy model of their building.

Chris Price

Education: Chris joined the TFCL in the Spring 2013 semester, after graduating from Johns Hopkins University. 

Research Interests control architectures for building HVAC systems. His research this past year has focused on studying the impact of cascaded control loops and their effects on system performance and stability. He is part of the NIST project and will be redesigning component control loops in order to facilitate the application of the MPC algorithms.

Erik Rodriguez

Education: Erik received his undergraduate degree at the University of Central Florida located in sunny Orlando, Florida. He joined the lab in the spring of 2011.

Research Interests His research has been focused around developing reduced order nonlinear heat exchanger models by using some of the insight provided by reduced order linearized models.

Kaimi Gao

Education: Kaimi earned her B.E. in Measuring and Control Tech. from Xi’an University of Technology. She came to Texas A&M in the fall of 2012 and joined the TFCL in April of 2013.

Research Interests Kaimi currently works on the DunAn Microstaq project evaluating their Silicon Expansion Valve technology.  Her focus is on experimental characterization of current valve capacity, utilization of a valve array to eliminate refrigerant mal-distribution, and a comprehensive set of experimental tests that will identify the most effective elements of an advanced valve control strategy.

Rawand Jalal

Education: Al‐Mustansiria University - College of Eng. ‐ Baghdad ‐ Iraq (Master of Science - Hydraulic Control - 2005 and Bachelor of Science - 2002).

Research Interests I joined the TFCL lab in Fall - 2012 and currently working on the NIST project. The main point in the research is to use Distributed Model Predictive Control (DMPC) mythology for controlling Heat, Ventilation and Air-Conditioning (HVAC) systems in buildings. Throughout a distributed fashion, we try to design a communication based agents to minimize the energy consumption by HVAC systems. Those agents try to minimize a given performance index subjected to actuator limitations and other restrictions that come from desired output performance and coupled constraints.

Rohit Chintala

Education: Texas A&M University - MS Mechanical Engineering

Research Interests: My research interests lie primarily in the area of control systems. I’m currently working on using system identification to create a model of the heating, ventilation and air-conditioning (HVAC) system of a working building. The model is created purely from empirical data, obtained through sensors. The sensors provide a time-series data of the various aspects of the HVAC system such as valve and damper openings, fan speed, discharge temperature etc. The model would then be used to implement a distributed model predictive control (DMPC) which optimizes a cost function while at the same time vastly reduces the communication burden which may result due to the large number of subsystems present in a building.

Trevor Terrill

Research Interests I am currently working on a direct Ph.D. and am in the second year of my program. Prior to coming to Texas A&M, I attended Brigham Young University in Provo, Utah. My assistantship is through the Industrial Assessment Center where we assess the energy usage of industrial facilities and make recommendations on how to reduce that usage. In my research, I am doing a long-term energy assessment of a church building and working on automating elements of industrial/commercial energy audits. I recently returned from Utah with Dr. Rasmussen for his faculty development leave where we performed several energy audits and worked on our long-term energy study
