GENERAL AVIATION FLIGHT LAB

Research & Publications

The GAFL strives to lead the curve in the field of adaptive, intelligent control systems. Over the years, our faculty and students have published numerous papers to globally-recognized journals, and have presented latest developments at major aerospace conferences. Our latest research areas and endeavors include:

  • Adaptive, neural network-based control systems for general aviation aircraft
  • Control systems resilient to loss of control effectivity and adverse weather
  • Unconventional aircraft control techniques (such as EEG control of aircraft, and control using interactive hand-motion gestures)
  • Simulated flight testing through small-scale R/C aircraft and full-scale flight simulators
  • Real-world flight testing of adaptive control algorithms
