Electrification of power systems is a societal megatrend, especially for vehicle systems such as aircraft, on- and off-road vehicles, and ships. There are currently many exciting opportunities for achieving higher performance and efficiency of electro-thermal systems through modeling and advanced control. As part of these efforts, this talk focuses a decentralized approach for modeling and control of energy systems with a particular emphasis on thermal management systems. First, a graph-based modeling framework is presented that is capable of capturing the dynamic behavior of complex systems as well as the structure of the coupling within the system. This modeling framework and system structure is then directly used to develop a decentralized model-based control scheme. A passivity-based approach is used to guarantee stability of the overall closed-loop system. Ongoing and future research efforts are presented that investigate the extension and application of this theory to achieve highly capable control of physical energy systems.
Dr. Justin Koeln received a B.S. degree in 2011 from Utah State University in Mechanical and Aerospace Engineering. He received M.S. and Ph.D. degrees in 2013 and 2016, respectively, from the University of Illinois at Urbana-Champaign in Mechanical Science and Engineering. Working with Professor Andrew Alleyne, his dissertation focused on hierarchical power management in vehicle systems. He is a member of the NSF Engineering Research Center for Power Optimization of Electro-Thermal Systems (POETS) with the long term goal of increasing power density of mobile electrified systems by 10-100 times greater than the current state-of-the-art. His research interests include modeling and control of thermal management systems, model predictive control, and hierarchical and distributed control for electro-thermal systems.
