Abstract:

Integrated fuel  cell power systems, especially those incorporating energy recuperating devices,  are often characterized by synergetic interactions of heterogeneous subsystems;  tight chemical, thermal, mechanical, and electrical couplings; and complex and  challenging control tasks. To maintain high efficiency, these systems often  operate on or close to their admissible boundary. In addition, there are many  operational constraints, such as continuous fuel cell reactant supply and  reactor temperature limits, that have to be strictly enforced during transient  operations.

In this  presentation, we will discuss our recent research and development activities on  modeling and control of integrated solid oxide fuel cell (SOFC) power systems.  We have focused our effort on developing control methodologies and tools that  can assure both highly efficient steady state operations and fast and safe  transients. Control-oriented modeling for the SOFC system will be discussed, in  conjunction with the control development results. Dynamic analysis and control  design of a hybrid SOFC and gas turbine power system will be presented.  Real-time simulation and optimization efforts will also be covered.

About  the speaker:

 Prof. Jing Sun received her Ph. D  degree from University of Southern  California in 1989. From 1989-1993, she was an  assistant professor in the Electrical and Computer Engineering Department at  Wayne State  University. She joined Ford Research Laboratory in 1993, where she worked on  advanced powertrain system controls. After spending almost 10 years in industry,  she came back to academia in 2003 and joined the Naval Architecture and Marine  Engineering Department and Electrical Engineering and Computer Science  Department at the University of Michigan where she is a professor now. She  holds 37 US patents and has co-authored (with  Petros Ioannou) a textbook on Robust Adaptive Control. She is an IEEE Fellow and  a recipient of the 2003 IEEE Control System Technology  Award.
