Dr. Hwang is an Associate Professor in the School of Aeronautics and Astronautics at Purdue University. He is a member
of Purdue's Signature Area for System-of-Systems research. He earned his Ph.D. degree, specialized in the area of multiple-vehicle
control and its application to air traffic control using hybrid systems approach, in the Department of Aeronautics and Astronautics
at Stanford University. He was a member of the Hybrid Systems Laboratory at Stanford University. He was a full time instructor in
the Department of Aerospace Engineering at Korea Air Force Academy from 1994 to 1997. He is an Associate Fellow of the American Institute
of Aeronautics and Astronautics (AIAA) and is a member of the Institute of Electrical and Electronics (IEEE) Control Systems Society.
He is currently an associate editor of the IEEE Transactions on Aerospace and Electronic Systems and Asian Journal of Control, an editorial board member of the International Journal of Aeronautical and Space Sciences (IJASS) and a conference editorial board member of IEEE Control Systems Society.
Dr. Hwang's research has been strongly motivated by difficult and interesting practical problems such as controlling multiple-vehicle systems.
Controlling multiple-vehicle systems is one of the most important and challenging aspects of modern system theory and practice. Control of such
systems involves the analysis of multiple dynamical systems which have inherently decentralized structures. The motions of vehicles have to be
coordinated in such a way that the vehicles achieve their goals without conflicts between them. This requires path planning (computing optimal
trajectories of vehicles from starting positions to destinations) and conflict detection and resolution. Path planning and conflict detection and
resolution require information about individual vehicles, and therefore communication between vehicles for sharing this information is important.
Multiple-vehicle systems encompass a variety of applications, including groups of Unmanned Aerial Vehicles (UAVs), Satellites, and mobile
robots; ad-hoc sensor networks; air traffic control.
Dr. Hwang is a head of the Flight Dynamics and Control/Hybrid Systems Laboratory.
