RRVS May 2020 Section Meeting


Dear valued IEEE member, 

Hope you are doing well during this difficult time and most of you are likely to be working remotely. To keep as normal as we can with our routine, we are offering this month’s Section meeting by WebEx at our regular monthly Section meeting time.  Due to the recent situation, we are unable to host face to face meetings and hope that this live WebEx meeting will bring a new experience and continue to give opportunities to members for networking and keeping current with technologies.


If you don’t have the application already, please download WebEx application on your desktop, laptop or mobile device before the meeting. Meeting will start at 7.00 PM. on May 28th, 2020.



Join us for the May section meeting.

Note: Due to the Coronavirus outbreak, this meeting is only available online. We will not be meeting face to face for the next couple of months.

Hierarchical Approach to Control of Complex Energy and Power Systems for Air Vehicles

Modern aircraft are highly complex systems.  This talk will present a particular hierarchical approach to energy and power flow in air vehicles that accommodates multiple power modes. These modes include thermal, fluid, electrical, or mechanical since these are all available in larger aircraft.  In particular, with the current drive towards increased electrification, the management of power onboard aircraft has become an enabler or a bottleneck depending on the point of view.  A key challenge in working across various modes of power flow is the widely varying time scales.  The hierarchy allows for systems operating on different time scales to be coordinated in a controllable manner. It also allows for different dynamic decision-making tools to be used at different levels of the hierarchy based on the needs of the physical systems under control. Additional advantages include the modularity and scalability inherent in the hierarchy.  Additional modules can be added or removed without changing the basic approach. In addition to the hierarchical control, a particularly useful graph-based approach will be introduced for the purpose of modeling the system interactions. The graph approach, like the hierarchy, has benefits of modularity and scalability along with being an efficient framework for representing systems of different time scales.  Recent results will be presented representing both generic interconnected complex systems as well as specific examples and resulting benefits.



Professor Andrew Alleyne received a B.S. Degree from Princeton in 1989 and his M.S. and Ph.D. degrees in 1992 and 1994, respectively, from U.C. Berkeley. He joined the University of Illinois, Urbana-Champaign in 1994 where he holds the Ralph & Catherine Fisher Professorship and is the Director of the NSF ERC on Power Optimization for Electro Thermal Systems (POETS). He is appointed in Mechanical Science & Engineering, Electrical & Computer Engineering as well as the Coordinated Science Laboratory. A Fulbright fellow, he has held visiting appointments at TU Delft, University of Colorado, Johannes Kepler University, and ETHZ. He is a recipient of the Gustus Larson Award and Henry Paynter Award from ASME. His research interests are a mix of theory and implementation with a broad application focus.
