Intelligent & High Assurance Autonomy for CPS

The research in the FD&C/HS Lab (Lab Director: Professor Inseok Hwang) focuses on two directions: fundamental research on Intelligent and High Assurance autonomy for the Cyber-Physical System (CPS), which is a complex (networked) system with interacting physical and logical components, using hybrid systems theory, and its applications to safety-critical aerospace systems such as aircraft, spacecraft, Unmanned Aircraft Systems (UAS), and Air Traffic Control (ATC), and multiple-vehicle systems (e.g., swarm of UAS). Note that aerospace systems are good examples of the CPS. For example, a UAS (similarly, aircraft and spacecraft) is composed of an autopilot which is a logical element and a vehicle that is a physical element, thus it is a CPS. (learn more)
