4. PROFESSIONAL EXPERIENCE
Assistant Research Scientist at the College of Engineering, University of Michigan 08/08-present
* Involved in collaborative work with PEEI (Pittsburg Electric Engine Inc.) to
develop mathematical model & control algorithm of turbocharged SOFC engines
for mobile applications in military ground vehicle, commercial heavy-duty
highway truck, and ship propulsion.
* Directed the instrumentation of a 5kW turbocharged fuel cell engine hardware
simulator, developed to investigate the technical feasibility of
commercializing a turbocharger and SOFC combined hybrid system and to
facilitate the system level control research. This is a jointly sponsored
research project by US Army TARDEC and US Navy NEEC program.
* Conducted a collaborative work with Alion Science and Technology Company for
a jp8 fuel reforming modeling and simulation with an emphasis on a hydrogen
storage and desulphurizer volume sensitivity analysis.
* Developed a motor/generator dual mode fuel cell-micro gas turbine system
equipped with an energy storage device (battery) to address the transient
issues such as fast part-load and fuel starvation.
* Wrote over 6 research proposals submitted to funding agencies and served as a
co-PI in 6 funded research grants
* Involved heavily in interdisciplinary research and collaborated with UM
faculty from mechanical engineering and naval architecture & marine
engineering; also collaborated with affiliated faculty at Automotive Research
Center, Univ. of Michigan.
* Collaborated closely with research engineers from US Amry TARDEC fuel cell
research team (Warren, MI).
Research Associate, Dept. of Naval Architecture & Marine Engineering,
University of Michigan, 08/06-08/08
* Responsibilities include mentoring graduate students, developing model-based
control algorithm, planning the experiment.
* Build MPC with constraint enforcement capability for ship maneuvering in
seaway while satisfying seakeeping constraints
* Led the autonomous model ship development project in a close collaboration
with research staff and engineers in MHL (Marine Hydrodynamics Lab). A
various ship path following algorithms – such as model predictive control,
backstepping, dynamic surface control, were successfully demonstrated on the
test bed in a UM MHL towing tank.
Research Assistant, Dept. of Mechanical Engineering, Mechanical Systems Laboratory, University of Delaware, 07/01-05/06
* Kinematic and dynamic modeling of dual-stage spatial cable-suspended robots
* Experimental facility setup of vertical planar and spatial cable-driven
robotic manipulators
* Flight control for autonomous landing of a helicopter on a rocking ship in
collaboration with Prof H. Pota in Australian Defense Force Academy (ADFA),
Australia.
