Aircraft energy systems are governed by nonlinear dynamics spanning multiple timescales and physical domains. They can be viewed as ‘systems-of-systems,’ forming complex networks of interconnected elements that convert, store, and exchange energy. Due to electrification and increasing on-board power demands, managing the thermal and electrical energy of these systems has become a significant challenge, limiting their capability, safety, and efficiency. This talk will present a hierarchical control framework for vehicle energy management that meets this challenge by facilitating the coordination of dynamics across multiple physical domains and timescales. Analysis methods ensure the stability and feasibility of this control framework, while experimental validation certifies its applicability as game-changing technology for advanced vehicles, bridging the theory-practice gap. Recent results to be presented include a hardware-in-the-loop implementation of electro-thermal hierarchical control and a decentralized passivity-based Model Predictive Control (MPC) approach that leverages the system structure to guarantee closed-loop stability, including under switching. These tools are applicable to conditions in which the environment serves as a heat sink, such as subsonic and supersonic aircraft, as well as a heat source, such as hypersonic and space systems. While the talk will focus primarily on the former, a brief discussion of the latter will be included.
About the Speaker
Herschel C. Pangborn is a PhD candidate, NSF Graduate Research Fellow, and Teaching Fellow at the University of Illinois at Urbana-Champaign. His research focuses on the dynamic modeling, optimization, and control of vehicle energy systems. He received a B.S. in Mechanical Engineering from Penn State University in 2013 and an M.S. in Mechanical Engineering from the University of Illinois in 2015. His research in the Alleyne Research Group has included collaborations with the Air Force Research Laboratory (AFRL), the NSF Engineering Research Center for Power Optimization of Electro-Thermal Systems (POETS), the Center for Integrated Thermal Management of Aerospace Vehicles (CITMAV), and the University of Illinois Air Conditioning and Refrigeration Center (ACRC). He is also an Engineering Consultant for CU Aerospace, supporting the Thermosys simulation toolset for analyzing the behavior of both single phase and phase-change thermal management systems. He is a Student Liaison for the Energy Systems Technical Committee (ESTC) of the ASME Dynamic Systems and Control Division (DSCD), and in this role has organized invited technical sessions and career development events at multiple ASME conferences.
